Project Information

Duportail Bridge Dwg

The Duportail Bridge is the final segment in the Duportail / Stevens Corridor strategy to provide improved multi-modal connectivity between central Richland and the Queensgate area.

The City began construction in March 2018 and anticipates opening the bridge to traffic in the summer of 2020.  

 This project is split into two phases, the bridge itself, and the intersection of SR240 and Duportail Street. For details on each phase, visit our Project Phases subpage.

  ** Project Updates**

For the duration of the project's construction, access to the river at the project site is restricted. This includes the boat launch and trail system. Please use alternate boat launches upstream and downstream from the project site. A detour to the trail route is in place and is signed accordingly.

March 2019 Update:

The month of February brought record amounts of snow and added some challenges and delays to the progress on the project. Even with the adverse weather conditions, reconstruction of the CID canal is nearly complete as the canal will be ready for water once irrigation season starts back up. Contractor completed Pier 2 columns and Pier 1 footing, and continuing to construct the two locations in preparation for setting of the concrete girders across all 5 spans this coming spring..

Apollo is also continuing to make progress on noise wall 2 (north of the Hills Mobile Home Park driveway) as approximately 80% of it is now completed, not counting the colored sealer to be applied later. Majority of the underground utility work (water, sewer, storm, some electrical) has also been completed, including the installation of the 42” ductile iron water main.
