Sound Transit begins work on Capitol Hill Station

Written by 

In early 2010, Seattle's Sound Transit will begin construction activities for the future Capitol Hill light rail station.  Before the station excavation can begin there are some early work activities that will be taking place over the next several weeks: 

• Closing a portion of E. Denny Way between Broadway and 10th avenues, and a portion of Nagle Place south of Denny. These road closures will be in effect for up to six years in order to accommodate the construction activities for the underground station.

• Installing tree protection around the Chinese Scholar Tree in Cal Anderson Park.

• Removing three trees in the northwest corner of Cal Anderson Park and several street trees along E. Denny Way.

• Installing the solid construction fence around the site.

• Relocating underground utilities on E. Denny Way, Howell, and Nagle Place. 

• Seattle DOT will install a new traffic signal at the intersection of Broadway Ave and E. Denny Way  

• "Jet grouting" the soil near E. Denny Way and John St., which involves injecting the soil with a cement-based substance to improve ground stability for tunneling.

Additional updates will be distributed as more information about the specific work and what to expect becomes available. 

University Link (U-Link) is the 3.15-mile extension of light rail from downtown Seattle to the University of Washington. U-Link includes twin-bore tunnels and two stations, one at Capitol Hill (Broadway Ave and E. John St) and the other on the University of Washington campus at Husky Stadium. U-Link is projected to add 70,000 daily riders to the Link system, bringing total daily ridership to 114,000 in 2030. Construction of U-Link began in early 2009 and will continue over the next six years. Passenger service is scheduled to begin in 2016.
