J Line Station

TYLin is providing the final design management for the RapidRide J Line Project in Seattle, Washington.

Improving transit travel time, reliability, and capacity, the RapidRide J Line Project is implementing bus rapid transit (BRT) along a 7-mile-long corridor serving neighborhoods from downtown Seattle to the University District. The project aims to increase all-day transit service and enhance the transit network. It will create improved pedestrian and bicycle connections with access to RapidRide stations, including protected lanes on Eastlake Avenue East and a two-way cycle track on Fairview Avenue North. 

The Seattle Department of Transportation (SDOT) is the lead agency on this project, which is being completed in cooperation with King County Metro. King County Metro will eventually own and operate the BRT facilities. Due to the size of the project, the corridor was split into three segments, each with its own discipline leads. TYLin provides overall coordination between the discipline leads and provides continuity to ensure standards are met, issues resolved, and the schedule is followed in design and plans. 

Project Highlights:

  • TYLin’s design management responsibilities encompass roadways, stations, stormwater, utilities, traffic signal and electrical service, trolley wire/Overhead Catenary System (OCS), traction power, structural, architectural, urban design, landscaping, environmental permitting, bidding assistance, and engineering services during construction.
  • The project includes grant application and management, value engineering, risk assessment, surveying, utility mapping, right of way resolution, geotechnical data gathering and analysis, station siting, constructability review, schedule development, and private development coordination.
  • RapidRide J Line is partially funded by the 9-year Levy to Move Seattle that voters approved in 2015. Additional funding is being sought through a Federal Transit Administration Small Starts Grant.
