Project Information

The City’s plan to build the Duportail Bridge is firming up with each passing month. The Bridge will be the final segment in the Duportail / Stevens Corridor strategy to provide improved multi-modal connectivity between central Richland and the Queensgate area. The bridge will include two vehicle travel lanes in each direction, with bicycle lanes and sidewalks on each side. Tanglewood Drive will connect Duportail Street to the residential developments to the north and the south. The intersection of Duportail Street and Tanglewood Drive will be controlled by a traffic signal. The intersection of Duportail Street and SR240 will be widened and improved, as will the at-grade railroad crossing on the Port of Benton Railroad. The project will also replace a water supply pipeline, currently located in the Yakima River, with two bridge-mounted pipelines.

Funding

Washington State’s Connecting Washington legislation, signed by Governor Inslee in 2015, provides $20,000,000 toward the project beginning in July, 2017. Other secured funds to date include $1,993,000 from FEMA for the water pipeline replacement and $4,500,000 for preliminary engineering, environmental reviews, and property acquisition. The City is actively seeking additional grants to assemble the remaining funding need of approximately $17,600,000. Additional opportunities will be pursued with the Washington State Department of Transportation, the Washington State Transportation Improvement Board, and the Benton Franklin Council of Governments. The City is planning to issue revenue bonds to complete the funding package once the available grant funding is assembled.

Schedule

The City intends to begin construction at the end of 2017 and open the bridge to traffic in the summer of 2020.  The construction process is arranged around limited opportunities to do construction work in the Yakima River.  The limitations are imposed for fish passage reasons by federal agencies.

Between now and the beginning of construction much important work remains.  The remaining work involves creating detailed engineering plans, acquiring property rights, confirming compliance with environmental requirements and obtaining permits.  The City has contracted with an experienced professional engineering team, led by BergerAbam Inc. of Federal Way to complete the engineering and permitting work.  City staff are negotiating the property acquisitions.

Project Benefits

Environmental Review Documents

The Federal Highway Administration issued a Finding of No Significant Impact for the Duportail Street Bridge project on May 29, 2013.  The Federal Emergency Management Agency issued a Finding of No Significant Impact for the project on May 16, 2013.  The U.S. Army Corps of Engineers issued a Finding of No Significant Impact for the project on June 20, 2014.

These findings were based on evaluation of the Environmental Assessment (EA) as issued March 3, 2013, and consideration of public comments during the comment period from March 3, 2013 through April 3, 2013. The public comment period included a public hearing on March 21, 2013.

Here are Electronic copies of the EA and FONSI. Printed copies are available at Richland City Hall and the Richland Public Library. Paper copies can be purchased for the cost of printing. The EA was based on a very thorough review documented in the following special studies.
