Round-End Kompak Model 97, Perey Manufacturing Company, 1946.
This Perey Round End Kompak model 97 is a refinement of the Square End Kompak, with an improved mechanical design. The top plate is constructed from stainless steel, reducing the maintenance on a high-wear area. Originally designed with a glass-windowed slug spotter at the intersection of the bands on the curved front, they were covered with metal plates after repeated vandalism. The turnstiles purchased by the IRT allowed people to exit through them, while those purchased by the BMT and IND were designed for entrance only. After numerous conversions of one-way turnstiles to two, only two-way turnstiles were ordered.

This is the Pont du Gard, a famous Roman Aqueduct on the Gardon River in France.
This monumental structure spanning the Gardon River valley is 275 metres long, 49 metres high, 6 metres wide at the base, 3 metres wide at the top and has a total of fifty three arches. It is only one part of a fifty kilometre aqueduct which supplied Roman Nimes with fresh water. It is estimated to have carried twenty thousand cubic metres per day.
It was built using six-ton stone blocks, coloured a delicate shade of pink, laid dry, and is a technological and aesthetic masterpiece.
Through poor maintenance, the aqueduct gradually became unusable in the 9th Century.
But the many times restored Pont du Gard, still remains its haughty air even after nearly two thousand years.

Begun around 19 BC, this bridge is part of an aqueduct which transported water from a spring near Uzes to Roman Nimes. An underground channel, bridges and tunnels were engineered to carry the 20 million litre (4.4 million gallon) daily water supply 50 km (31 miles).
The three-tiered structure of the Pont du Gard spans the Gardon valley and was the tallest aqueduct in the Roman empire.
Its huge limestone blocks, some as heavy as 6 tonnes, were erected without mortar. The water channel covered by stone slabs, was in the top tier of the three. Skillfully designed cutwaters ensured that the bridge has resisted many violent floods.
It is not known for certain how long the aqueduct continued in use but it may still have been functioning as late as the 9th century AD.
The adjacent road bridge was erected in the 1700s.

Ancien Chemin d'Aix | Canal de Marseille 06/06/2013 10h47
Along the site of the gîte we were staying and the Ancien Chemin d'Aix there is this canal, the Canal de Marseille with its almost turquoise colored water.
Photo taken when we started to make our circled tour around the Montagne Sainte-Victoire.
Canal de Marseille
The Canal de Marseille is a major source of drinking water for the city of Marseille, the largest city in Provence, France. The canal's length along its main artery is 80 kilometres - though there is an additional 160 kilometres of minor arteries - and it services the entire district of Marseille. It took fifteen years of construction under the direction of engineer Franz Mayor de Montricher, and opened on July 8, 1849. It represents a significant achievement in nineteenth century engineering, combining bridges, tunnels, and reservoirs to create a canal over mountainous terrain. Until 1970, it was almost the sole water source for Marseille and currently provides two-thirds of the city's drinking water.
Marseille, located along the hilly Mediterranean seafront is only crossed by one irregular river, the Huveaune River, and its tributary, the Jarret River. The waters were canalized in the 14th century, but over time became an open sewer. Water quality continued to decline and the distribution suffered due to lack of maintenance on the network.
Further, since the river suffered from a weak flow droughts were devastating to the region. For example, in 1834 the river nearly dried out completely and only 1 litre was available per person, per day. In the 1830s, Marseille began to experience rapid population growth and in 1832-1835 epidemics of cholera convinced elected officials to act to restore health and ensure an appropriate quantity of water for the city.
The building of the canal took 15 years, from 1839–1854 and covered 80 kilometres of which 17 kilometres were underground. The canal also traverses 18 bridges.
After Lambesc, the canal's path becomes more complex: many bridges and tunnels are required to travel the valleys and near Coudoux. The canal bypasses the hill Ventabren, and comes to the Arc where it enters the aqueduct Roquefavour. Near this area, the Paris-Marseille line of the TGV passes and the railway's viaducts have been designed to harmonize with the aqueduct.

The Chesapeake Bay Bridge–Tunnel (CBBT) is a 23-mile-long (37 km) fixed link crossing the mouth of the United States Chesapeake Bay and connecting the Delmarva Peninsula's Eastern Shore of the state of Virginia with Virginia Beach and the metropolitan area of Hampton Roads, Virginia.
The bridge–tunnel originally combined 12 miles (19 km) of trestle, two 1-mile-long (1.6 km) tunnels, four artificial islands, four high-level bridges, approximately 2 miles (3.2 km) of causeway, and 5.5 miles (8.9 km) of approach roads—crossing the Chesapeake Bay and preserving traffic on the Thimble Shoals and Chesapeake shipping channels. It replaced vehicle ferry services which operated from South Hampton Roads and from the Virginia Peninsula from the 1930s until completion of the bridge–tunnel in 1964. The system remains one of only ten bridge–tunnel systems in the world, three of which are located in Hampton Roads, Virginia.
The CBBT complex carries U.S. Route 13, the main north–south highway on Virginia's Eastern Shore, and, as part of the East Coast's longstanding Ocean Highway, provides the only direct link between the Eastern Shore and South Hampton Roads regions, as well as an alternate route to link the Northeast and points in between with Norfolk and the Carolinas. The bridge–tunnel saves motorists 95 miles (153 km) and 1½ hours on a trip between Virginia Beach/Norfolk and points north and east of the Delaware Valley without going through the traffic congestion in the Baltimore–Washington Metropolitan Area.
Initially, high-level bridges were contemplated to cross over the two main shipping channels on the selected route, Thimble Shoals Channel, which leads to Hampton Roads, and the Chesapeake Channel, which leads to points north in the Bay, notably the Port of Baltimore. However, the U.S. Navy objected, due to concerns that collapse of high level bridge(s) (due to either accidental or deliberate action) could cause a large portion of the Atlantic fleet based at the Norfolk Navy Base at Sewell's Point and other craft within the Hampton Roads harbor area to be blocked from access to the Atlantic Ocean.
To address these concerns, the engineers recommended a series of bridges and tunnels known as a bridge–tunnel, similar in design to the Hampton Roads Bridge–Tunnel, which had been completed in 1957, but a considerably longer and larger facility. The tunnel portions, anchored by four man-made islands of approximately 5 acres (2.0 ha) each, would be extended under the two main shipping channels.

WWL ALS successfully completes transport of the widest loads since records began through central London
Location: Central London – Canary Wharf in background
Description:
In May, 2013 Dragados Sisk Joint Venture (DSJV), the contractor constructing Crossrail’s Eastern running tunnels, approached WWL ALS (Wallenius Wilhelmsen Logistics Abnormal Load Services UK International Limited) to discuss the practicality of delivering Tunnel Boring Machine (TBM) ‘Jessica’ from Stepney Green, east London through to Limmo Peninsular, east London as part of the Crossrail Eastern Tunnels contract C305.
The challenge from DSJV was to transport the 1,300 tonne Herrenknecht S-721 TBM and back-up equipment in as large individual components as possible to enable DSJV to achieve the relocation quickly, efficiently and cost-effectively.
For such a large-scale project nine months of intensive planning was required to determine a suitable route, obtain permits and liaise with multiple statutory authorities regarding the removal of street furniture, traffic management and street parking suspensions. The process required WWL ALS’ Project team to secure the necessary Be16 Special Order, VR1 and TTRO permits.
Extensive surveys were undertaken by WWL ALS to determine possible routes for this project. As part of this planning process innovative 3 dimensional laser mapping was used on dual carriageway sectors of the route with high traffic density, for scanning overhead gantry, bridge and tunnel heights and widths where manual means of checking clearances would be too hazardous.
Two optional routes were identified, and the least problematic option was selected to cause minimal disruption to residents and other road users. The route taken by all loads was eastbound via the A13 Limehouse Link Tunnel, with a height and width clearance of just a few centimetres for the largest items, and it also involved travelling contra-flow on a 750m section of this major arterial route (A13) for the two largest loads.
WWL ALS’ project team, headquartered in Hull, organised and closely supervised deliveries over a four week period for this challenging operation, concluding in April, 2014. TBM ‘Jessica’, which was dismantled and transported by road two months after completing a 2.7 kilometre underground drive from Pudding Mill Lane, involved a total of 26 x abnormal loads plus ancillary equipment. Due to the congested nature of the inner-city route, between seven and twelve police escort vehicles were required for each abnormal load movement in addition to the private escorts provided by WWL ALS.
An assortment of low loader and semi low loader vehicles were used, with a maximum gross vehicle weight (GVW) of 114 Tonnes, and the time taken from collection to delivery of cargo was on average 90 minutes per movement. The largest items were transported towards the end of the project, involving loads with maximum dimensions up to 18.20 metres long, 7.10 metres diameter wide, 4.35 metres high and maximum weight 72 tonnes. The Metropolitan Police have commented that “these were the widest loads moved within central London since records began”.
WWL ALS’ Project team ensured that TBM ‘Jessica’ made the smooth 5 kilometre journey from one of Europe’s largest mined caverns at Stepney Green to Limmo Peninsular (Canning Town), east London within the scheduled timescale and budget for the project, where the TBM has been reassembled to commence work on the final Crossrail tunnels between Limmo Peninsular and Victoria Dock.
Within the next month WWL ALS will commence the relocation of TBM ‘Ellie’ (a sister machine to TBM ‘Jessica’), again from Stepney Green to Limmo Peninsular.

Begun around 19 BC, this bridge is part of an aqueduct which transported water from a spring near Uzes to Roman Nimes. An underground channel, bridges and tunnels were engineered to carry the 20 million litre (4.4 million gallon) daily water supply 50 km (31 miles).
The three-tiered structure of the Pont du Gard spans the Gardon valley and was the tallest aqueduct in the Roman empire.
Its huge limestone blocks, some as heavy as 6 tonnes, were erected without mortar. The water channel covered by stone slabs, was in the top tier of the three. Skillfully designed cutwaters ensured that the bridge has resisted many violent floods.
It is not known for certain how long the aqueduct continued in use but it may still have been functioning as late as the 9th century AD.

From a tourist book on La Provence (English version)
Begun around 19 BC, this bridge is part of an aqueduct which transported water from a spring near Uzes to Roman Nimes. An underground channel, bridges and tunnels were engineered to carry the 20 million litre (4.4 million gallon) daily water supply 50 km (31 miles).
The three-tiered structure of the Pont du Gard spans the Gardon valley and was the tallest aqueduct in the Roman empire.
Its huge limestone blocks, some as heavy as 6 tonnes, were erected without mortar. The water channel covered by stone slabs, was in the top tier of the three. Skillfully designed cutwaters ensured that the bridge has resisted many violent floods.
It is not known for certain how long the aqueduct continued in use but it may still have been functioning as late as the 9th century AD.
The adjacent road bridge was erected in the 1700s.

MTA Bridges and Tunnels is sprucing up its toll plazas, repainting toll booths at all nine crossings a uniform and familiar color, MTA blue. The actual color is called “safety blue” but it happens to also coincides closely with the color of the MTA logo. The last time all 150 toll booths and their surrounding concrete islands, curbs, and bullnoses were painted was 2001.

Fellow "Flickr-holic" Bridges and Tunnels and I took our annual trip to Sydney's Northwest on 29 December 2015 to review progress on Metro Northwest (AKA the North West Rail Link).

Chesapeake Grill & Virginia Originals is a restaurant and gift shop located on One Island on the Bay/Sea Gull Island, the southernmost of the Chesapeake Bay Bridge-Tunnel's four man-made islands.
The Chesapeake Bay Bridge-Tunnel (CBBT) is a 23-mile (37 km) long fixed link crossing the mouth of the Chesapeake Bay and connecting the Delmarva Peninsula's Eastern Shore of Virginia with Virginia Beach and the metropolitan area of Hampton Roads, Virginia. It replaced vehicle ferry services which operated from South Hampton Roads and from the Virginia Peninsula from the 1930s until completion of the bridge-tunnel in 1964.
The bridge-tunnel originally combined 12 miles (19 km) of trestle, two 1-mile (1.6 km) long tunnels, four artificial islands, two high-level bridges, approximately 2 miles (3.2 km) of causeway, and 5.5 miles (8.9 km) of approach roads—crossing the Chesapeake Bay and preserving traffic on the Thimble Shoals and Chesapeake shipping channels. The system remains one of only eight bridge-tunnel systems in the world, three of which are located in Hampton Roads, Virginia.
Since it opened, the Chesapeake Bay Bridge-Tunnel has been crossed by more than 100 million vehicles. The CBBT complex carries U.S. Route 13, the main north–south highway on Virginia's Eastern Shore, and, as part of the East Coast's longstanding Ocean Highway, provides the only direct link between Virginia's Eastern Shore and South Hampton Roads regions, as well as an alternate route to link the Northeast and points in between with Norfolk and the Carolinas. The bridge-tunnel saves motorists 95 miles (153 km) and 1½ hours on a trip between Virginia Beach/Norfolk and points north and east of the Delaware Valley without going through the traffic congestion in the Baltimore–Washington Metropolitan Area. The $12 toll is partially offset by some savings of tolls in Maryland and Delaware on I-95.
Financed by toll revenue bonds, the bridge-tunnel was opened on April 15, 1964. It was officially named the Lucius J. Kellam Jr. Bridge-Tunnel in August 1987 after one of the civic leaders who had long worked for its development and operation. However, it continues to be best known as the Chesapeake Bay Bridge-Tunnel.
From 1995 to 1999, at a cost of almost $200 million, the capacity of the above-water portion was increased to four lanes. An upgrade of the two-lane tunnels was proposed but has not been carried out.
The CBBT was built by and is operated by the Chesapeake Bay Bridge and Tunnel District, a political subdivision of the Commonwealth of Virginia governed by the Chesapeake Bay Bridge and Tunnel Commission. The CBBT's costs are recovered through toll collections. In 2002, a Joint Legislative Audit and Review Commission (JLARC) study commissioned by the Virginia General Assembly concluded that "given the inability of the state to fund future capital requirements of the CBBT, the District and Commission should be retained to operate and maintain the Bridge-Tunnel as a toll facility in perpetuity."
The Brooklyn-Battery Tunnel passes underwater and off-shore of Governors Island's northeast corner, its location marked by an octagonal air ventilation building connected to the island by a causeway.
Old Elbe Tunnel or St. Pauli Elbe Tunnel (Alter Elbtunnel colloquially or St. Pauli Elbtunnel officially) which opened in 1911, is a pedestrian and vehicle tunnel in Hamburg, Germany. The 426 m long tunnel was a technical sensation; 24 m beneath the surface, two 6 m diameter tubes connect central Hamburg with the docks and shipyards on the south side of the river Elbe. This was a big improvement for tens of thousands of workers in one of the busiest harbors in the world.
Four large lifts on either side of the tunnel carry pedestrians and vehicles to the bottom. The two tunnels are both still in operation, though due to their limited capacity by today's standards, other bridges and tunnels have been built and taken over most of the traffic.
In 2008 approximately 300,000 cars, 63,000 bicycles, and 700,000 pedestrians used the tunnel. The tunnel is opened 24 hours for pedestrians and bicycles. For motorized vehicles, opening times are currently Monday to Friday from 5:20 AM to 8:00 PM and on Saturdays from 5:20 AM to 4:00 PM. Source: en.wikipedia.org
1939 World's Fair Turnstile, Percy Manufacturing Company
A modified version of the BMT Coinpassor was built for the IND's temporary 1939 World's Fair subway station. A dime, twice the normal fare, was required to access this special station. The turnstiles had coin slots at both ends of the device and passengers deposited a dime on entering or a nickel on exiting the station.
The New York Transit Museum, located in the decommissioned Court Street subway station at Boerum Place, was opened 1976 by the New York City Transit Authority and taken over in the mid-1990s by the Metropolitan Transportation Authority (MTA). The museum includes subway, bus, railway, bridge, and tunnel memorabilia; and other exhibits including vintage signage and in-vehicle advertisements; and models and dioramas of subway, bus, and other equipment.
