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.

June 2019 Update:

The first bridge deck span (Span 5) concrete was poured at the end of June, marking yet another important milestone for the project! This is the first of five bridge deck spans, and the Contractor is continuing work and preparation for the next span, which includes formwork and rebar installation, with hopes of pouring concrete for Span 4 in July. Each bridge deck is supported by 10 pre-stressed concrete girders that span between piers.

Apollo has also now completed both noise walls 1 & 2 along the Hills Mobile Home Park vicinity. Colored sealer will be applied to these walls, which is scheduled to happen in July. Work is also progressing on concrete wall 5, the ”Sun Wall” as the Contractor is preparing formwork with architectural liners, as well as reinforcing steel installation. 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.
