Deweyville Swing Bridge – Deweyville TX


The Deweyville Swing Bridge is built over the Sabine River where Texas State Highway 12 and Louisiana Highway 12 meet. The bridge is a deck plate girder swing design. The 160 foot main span pivots on top of a central pillar.

Congress passed the Emergency Relief Appropriation Act on April 8, 1935. This act gave states grant money for road and bridge construction.

The bridge opened on March 10, 1938. The bridge is opened manually by workers using a massive T-wrench inserted in a hole in the middle of the bridge and turned. Regular openings of the bridge ceased in the 1960s due to lack of river traffic. The bridge last opened in 1995. The bridge stills carries vehicular traffic and was listed on the National Register of Historic Places on June 8, 2011.

    I am trying to find out when the bridge was used to move a houseboat on the Sabine River. The owner of the boat was Jack Rowe. I thought it was late 80’s but not sure. Can you help me?
