We're pouring concrete in Aberdeen to build the pontoons for the worlds longest floating bridge. This is a view from one of the construction cranes. Once they're finished the pontoons will be floated into Grays Harbor and towed around the Olympic Peninsula to Lake Washington.
This is a map of the residential district where we have lived, more-or-less, since 1996.
YELLOW: Privately-held residential land.
LIGHT GREEN: 100 year-old city parks.
RED-ORANGE: Public lake.
ORANGE: Trans-Continental Superhighway
DARK GREEN: Pavement and lands beyond the district.
WHITE RING: The psycho-geographic boundaries of our home district.
PHYSICAL & SOCIAL CHARACTERISTICS:
It takes about twenty minutes to walk across this district from the north or south (from the top or bottom of the map.) The district is home to about 1,500 residents. Nearly all the households here have median incomes above the local average. Several households, particularly along the lake shore, have incomes considerably higher than the average.
The soil is a glacial moraine piled into a ridge during the last ice age, about 15,000 years ago. The icesheets, over half a mile thick, also scooped out the lake basin. The district sits on the slope beside the lake, dropping about 200 feet (65 m.) from the top of the ridge (where the DARK GREEN meets YELLOW) down to the shore (where the YELLOW meets RED).
The district has been urbanized (or suburbanized) for roughly 100 years.
The superhighway is housed mostly in a suite of massive tunnels beneath the ground surface of the district. Many tens of thousands of high-speed vehicles traverse the district through the subterranean superhighway each day. East of the tunnels, floating bridges carry the superhighway and its traffic across a five mile lake span. Though the highway complex was rennovated and expanded at significant public expense and considerable disruption to surrounding neighborhoods about twenty years ago, it retains many of the basic structural features from its debut in 1940: tunnels, floating bridges, etc. There is a small park situated above the eastern tunnel openings called East Portal Park. Above the tunels is inscribed the motto, "Gateway to the Pacific'. The little park offers seating and viewing for visitors to experience the visceral rush and howl of a dozen lanes of traffic passing near one's body at full freeway speed.
The house and patch of land we own is located in the bottom left-hand region of the map, between the super-highway and the southern park, about a quarter of the way down the ridge. From here, tires upon the superhighway produce a constant roar like crashing surf.
Within two years of the end of WII, the City of Seattle granted a sewer connection permit at this address, linking a wide array of public assets and infrastructure to the home we now occupy.

This photo shows the floating barge the divers use while inspecting the new SR 520 pontoons. Moored next to the in-service floating bridge, the barge houses the shack where the inspector observes the dive first-hand via a live video feed and two way communication with the diver.
As the new SR 520 floating bridge takes shape, crews continue thorough inspections of the concrete pontoons that will serve as the floating foundation. On Nov. 30, 2012, a photographer snapped these shots of an underwater inspection in progress on Lake Washington. The diver scanned the underside of Pontoon W, the eastern cross pontoon, and kept in constant communication with an inspector who maps out the condition of the pontoons. WSDOT will continue to inspect the new pontoons as part of its commitment to delivering a safe, durable bridge that will last 75 years or more.

Sailboat “Long Time” was the last boat to use the drawspan in the existing SR 520 floating bridge before crews permanently blocked it with construction activities for the new SR 520 floating bridge. The new bridge will not have a drawspan, but will have a navigational height clearance of 70-feet, similar to the I-90 East Channel bridge.
More information about the new SR 520 floating bridge is available on our website. You may also find additional information regarding marine navigation changes on Lake Washington on our Boater Information Web page.
The new SR 520 West Connection Bridge will connect the new floating bridge with the existing SR 520 bridge. When the new West Approach Bridge North is completed, the West Connection Bridge will carry three lanes of eastbound traffic.
Over the weekend of May 30 to June 2, SR 520 was closed for SR 520 West Connection Bridge construction. The West Connection Bridge will connect the new floating bridge to the existing west approach. Find out more about the new SR 520 on our website.
Crews working on the West Connection Bridge this weekend pour concrete to construct two roadway deck sections for the new 1,330-foot interim bridge. After this weekend, three of eleven roadway deck sections will be complete.

Sasamat Lake Trail:
The trail wraps around the lake so you can choose what area you would like to begin your walk. However, from White Pine Beach area as you walk down the short hill towards the beach, the lake comes into full view giving a sense of the entire area and the distance around the lake. Go right towards the end of the beach area where the paved trail turns to gravel and heads into the forest.
For the first section the well maintained trail hugs the shoreline offering occasional glimpses of the lake from different angles. As you continue, the trails goes up a set of wooden stairs and merges with the gravel road above. Follow this road to the left towards the Sasamat Outdoor Club, a facility that offers many outdoor programs for community groups and local schools within the Belcarra Park area.
Cross the driveway and walk down the steps as the trail continues toward Bedwell Bay Road. After crossing a bridge over a small stream, the trail reaches a junction. Walking right takes you to Woodhaven Swamp and going left will continue along the trail that circles the lake.
Go right as the trail follows Bedwell Bay Road for a short distance before going up a set of wooden stairs to the road. Carefully cross the road to the sign on the other side and continue up the trail between the two residential houses. The trail is well maintained and easy to follow through the second-generation of Douglas Fir and Western Cedar trees.
After hiking for 2km, the trail arrives at another small road with the Woodhaven Swamp partially visible between the trees on the other side. Cross the road and continue along the trail to a sign on the left. Walk down the steps and follow the path as it loops around the swamp area.
After enjoying the scenery, return to the road area and cross back to the trail that leads back down towards Sasamat Lake.

The Pontoon construction basin is empty following the final float out of Cycle 6 pontoons on March 10.
WSDOT and contractor Kiewit-General marked a major milestone in Aberdeen on March 9, 2015, as crews prepared to float out the final three pontoons for the new SR 520 floating bridge. Several elected officials, community members, and even the Aberdeen High School marching band participated in the event at the casting basin facility. These three pontoons represent the last of the 77 pontoons needed for the new floating bridge, and mark the completion of all six cycles built in Aberdeen. Next, the three pontoons will be inspected and then towed to Lake Washington where they will be joined together to form the foundation of the new floating bridge. The new bridge is scheduled to open in spring 2016.
The six pontoons under construction in Aberdeen neared completion on Feb. 24, 2014. Once complete, they will be floated out of the casting basin and into Grays Harbor, and eventually towed to their final location as part of the new SR 520 floating bridge in Seattle.
Construction crews are underway on the fourth cycle of SR 520 bridge pontoons in Aberdeen. In this cycle, crews will build six total pontoons:
• Four longitudinal pontoons (360 ft. x 75 ft. x 29 ft.)
• Two supplemental stability pontoons (98 ft. x 60 ft. x 28 ft.)
With the gate removed, water filled the basin in preparation for the float-out. Before tug boats can tow these pontoons from the basin, a special "T pontoon" is brought in to provide the extra floatation needed to bring them into the open water. Photo taken Jan. 28, 2013.
Plenty of activity is happening as construction of the new SR 520 bridge continues. In this photo we can see the columns on pontoon W rise above Lake Washington and the north and south columns of Pier 2 take shape.
In this image we can see work continuing on both columns of Pier 2 with pontoon W and the current SR 520 bridge in the background.

If you were to drive from Seattle-to-Boston by way of Chicago in a direct manner, this is probably where you would begin, on Interstate 90 driving across Lake Washington.
This location is not far from where I live; I can walk to it, albeit via a long walk. I haven't been at this photographic point in a long time.
The middle lane is being converted for light rail. I think that line is due to open in 3-4 years. It might be interesting on the next sunny morning to pay this point a visit and see how far they've come with the new rail line.
Tow lines from tugboat West Point are secured to Pontoon S just before midnight, April 28, 2013. When Grays Harbor's tidal waters reach the right level the pontoon will begin to float for the first time and West Point will tow the massive concrete pontoon from the casting basin.
Progress continues on the SR 520 Pontoon Construction Project, as the second cycle of new pontoons left the Aberdeen casting basin overnight April 28 and 29, 2013. The late-night timing coincided with the favorable high tide needed for float-out.
In the second cycle, crews built three longitudinal pontoons, two supplemental stability pontoons and one cross pontoon. The 360-foot-long longitudinal pontoons are the backbone of the new SR 520 floating bridge being built on Lake Washington; the supplemental pontoons provide stability and flotation, and the cross pontoons cap the bridge on the east and west ends. Crews will build a total of six cycles of new pontoons in Aberdeen.
One of the crew works safely in a basket on the outside of the barrier. The existing east approach can be seen in the background.
Tugboats line up in the Chehalis River launch channel, ready to help tow pontoons from the Aberdeen casting basin.
Construction crews working on the SR 520 Pontoon Construction Project took advantage of an extra-high tide Oct. 5, 2013, to float six concrete pontoons into the Chehalis River. These pontoons comprise the third of six pontoon construction cycles and are destined for Lake Washington to form the backbone of the new SR 520 floating bridge.
Crews precisely place the first concrete section of a 130-foot-long concrete culvert that will run underneath SR 520 in Bellevue.
Crews quickly carved a 30-foot-deep trench across SR 520 west of Bellevue Way Northeast to install the new, larger culvert. The culvert will improve fish migration and is the first of eight culverts crossing SR 520 that will be installed between Medina and Bellevue during the next three years.
In this image we can see the progress construction crews have made on Pier 1 as the north and south columns rise above Lake Washington and the cofferdam. Take a look at our photo from Feb. 8, 2013 and see the difference!
A 38-foot pleasure boat was found to be wedged underneath the SR 520 floating bridge, near the west highrise at 8 p.m. on March 21, 2011.
Fire crews and the Seattle Harbor Patrol did their job and extricated the two people on board the boat. When that was done, a WSDOT bridge maintenance team began its work - inspecting the bridge for damage. They could not see much in the dark so they returned in the daylight hours of March 22, 2011.
With only about five feet of clearance between the water and the concrete beams under the bridge, the maintenance crew used a small workboat to get under the bridge. The space was so tight, the crew needed to lower the windshield on their boat to squeeze underneath.
They determined the boat/bridge collision did not lead to any structural damage. The scrapes and scuffing are cosmetic and superficial.
It’s unclear why the boaters tried to pass under the bridge near the sculptures at the west end where the underside of the bridge is only a few feet off the water. The clearance under the west highrise for boaters is 45 feet. Navigation information for the bridge can be found at www.wsdot.wa.gov/traffic/bridges/sr520/marineinfo.htm
The rescue of the boaters required the closure of one eastbound lane of SR 520 for several hours. WSDOT will submit a bill for the costs incurred for blocking off a lane and evening inspection work to the boater or insurance company.

Crews were installing post-tensioning strand in the pontoon tendons on Feb. 24, 2014. These tendons will be tightened to add strength to the pontoons.
Construction crews are underway on the fourth cycle of SR 520 bridge pontoons in Aberdeen. In this cycle, crews will build six total pontoons:
• Four longitudinal pontoons (360 ft. x 75 ft. x 29 ft.)
• Two supplemental stability pontoons (98 ft. x 60 ft. x 28 ft.)
Suspended over 20 feet above the pontoon's keel, ironworkers build the complex inner steel structure that provides the pontoon with its strength. Photo taken June 20, 2013 at the pontoon construction site in Aberdeen, WA.
Construction crews are underway on the third cycle of SR 520 bridge pontoons in Aberdeen. In this cycle, crews will build six total pontoons:

Construction is complete on the second cycle of SR 520 bridge pontoons in Aberdeen. In this cycle, crews built six total pontoons:
• Three longitudinal pontoons (360 ft. x 75 ft. x 29 ft.)
• One cross pontoon (270 ft. x 75 ft. x 33 ft.)
• Two supplemental stability pontoons (98 ft. x 60 ft. x 28 ft.)
Work continues at Pier two as construction crews prepare the south column for the first installation of roadway for the new SR 520 bridge in the next few weeks. We can see the changes compared with a photo we took Jan. 31.
