Duportail Extension
Robert Ave to Wellsian Way
The City of Richland's Duportail Extension project was selected for funding in November 2013. TIB contributed $1,819,442 in funding toward the $1,957,520 total cost of the project.
The project reconfigures the Thayer Drive/Duportail Street intersection with a single-lane roundabout. Duportail Street will extend from Thayer Drive to Wellhouse Loop to provide two travel lanes, a two-way center left turn lane, bike lanes and sidewalk on both sides of the street. A new signal will also be constructed at the intersection of Duportail Street and Wellsian Way.
