Duportail Bridge Groundbreaking EventBridge Groundbreaking

The Duportail Bridge Project is officially underway! 

On Wednesday, February 28, 2018, Richland residents, council members, staff and various agency representatives came together to kick off the Duportail Bridge project. Also in attendance were representatives from Apollo, Inc., the awarded contractor tasked with Connecting Richland.

Thank you to everyone who joined us in this celebration! 


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.
