Construction of a new section of Northeast 10th Street that will eventually provide new access to the Overlake Hospital Medical Center campus and across Interstate 405 has begun. When the first stage of the project is complete, scheduled for the spring of 2008, 10th Street will extend from 116th Avenue Northeast between Overlake's South Tower and the Group Health Bellevue Medical Center (both currently under construction) to the eastern edge of I-405.
The City of Bellevue contracted with Scarsella Brothers, Inc., of Seattle to complete the first stage of the project. Scarsella Brothers' $7.1 million bid was approximately 14 percent below engineers' estimates. Scarsella started on the project in mid-December.
In the second stage of the project, set to begin in early 2008, the state Department of Transportation will build an overpass for 10th Street to extend across I-405 to 112th Avenue Northeast. This will provide improved access in the north end of downtown Bellevue and help relieve congestion on Northeast Eighth Street.
The majority of the funding for the $67 million project comes from WSDOT's Transportation Partnership Account. Federal money accounts for approximately 18 percent of project funding.
The first phase of the Northeast 10th Street Extension will include widening 116th Avenue Northeast, from Northeast Eighth Street to the Overlake and Group Health entrances. The work will add one lane along 116th to the west. During construction, the two-way left turn lane along that section of 116th will close.
To maintain safety and traffic flow, mid-block vehicle movement will be restricted to right-turns only. Left turns will be allowed at signalized intersections.
Other than the turn restrictions on 116th, the first stage of the project will have minimal traffic impacts for the traveling public and users of the hospital. In summary:
- Through traffic on 116th Avenue Northeast will generally be maintained, with some lane closures for construction.
- Turn lanes at Northeast Eighth/116th Avenue Northeast and at the existing signalized hospital entrance will be maintained.
- The city Transportation Department is working with the hospital and Fire Department to ensure continued emergency vehicle access.
- Road construction noise impacts are not likely to exceed impacts from hospital construction itself. There will be some night work (utility work, paving, etc.) on 116th Avenue Northeast, with some noise.
The City of Bellevue, WSDOT, Overlake Hospital and Group Health Cooperative are closely coordinating construction on the two medical center expansions and the road projects, collectively known as the Northeast 10th Medical District.
