I-90 Undercrossing plan is moving forward

February 3, 2009

The city received a draft maintenance agreement last month from the state Department of Transportation for the I-90 Undercrossing Project. After some minor edits, the document was sent  back for review and approval, said Bob Brock, the city’s director of Public Works.

“The next step will be for the final agreement to be brought to the City Council as an agenda bill, likely in March,” he said. “Once fully executed, the city could advertise for construction of the segment under I-90.” 

The city owns property formerly owned by Zetec, an industrial equipment company that it is marketing to a developer to then redevelop, Brock said.

“Our goal is to have a bridge over the North Fork of Issaquah Creek and to begin the bridge over the creek in July,” he said during a Jan. 27 briefing before the City Council’s Committee of the Whole.

State transportation officials are trying to determine how best to plan for the future of Interstate 90 between Interstate 405 and North Bend. The effort is known as the I-90 Corridor Study. Funded at $2 million from gas taxes by the 2005 Legislature, the study is a tool to identify how, where and when highway improvements should be made.

Congestion on the freeway lasts three hours during the morning commute and two hours in the evening, according to highway officials.

Transportation officials want a new crossing under I-90 between the Sunset Interchange and state Route 900. The city’s planned I-90 Undercrossing, from Gilman Boulevard at the post office, has been designed and permitted.

Post office officials are working on a traffic study for the commercial lot they plan to develop. Depending on the required mitigation, their impacts will possibly justify a dedication of right of way for the I-90 project, Brock said.

“Our goal is to find a point of mutual agreement on the mitigations that are needed for their development project,” he said.
