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.

April 2019 Update:

April was an exciting month as all 50 pre-stressed concrete girders were delivered and set across all 5 spans of the bridge, utilizing Lampson’s massive Transi-Lift 1100 crane, and marking an important milestone for the project. Contractor will be continuing work on the superstructure, which will include falsework, rebar, and concrete installation at each of the 5 spans. In the meantime, work on two retaining walls, located in vicinity of the south bridge approach slab area, has also begun as concrete footings were poured.

Apollo is also continuing to make progress on noise wall 2 (north of the Hills Mobile Home Park driveway) as approximately 95% 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.
