Galveston causeway

There are two causeways connecting Galveston Island to the mainland. Both have been renovated over time with changes consisting of wider lanes and a drawbridge replacement.

The original Galveston Causeway was opened in 1912 and is now restricted to railroad use only. The companies, Gould Lines, Harriman Lines & Santa Fe, originally owned it. This railroad bridge is considered one of the greatest accomplishments of engineering in the United States and was put on the list of the National Register of Historic Places in 1976.

The second causeway debuted in 1939 at an approximately $3,000,000 price tag and is 8,194 feet long. The bridge was replaced and completed in 2005, and it is the only access for northbound and southbound traffic on the Interstate 45.
