NE 3rd/4th Street Corridor Improvements: Phase 1 Intersection Improvements (New Traffic Signal at NE 4th Street & Whitman Court NE)

Project Manager – Keith Woolley, 425-430-7318

Description – The NE 3rd/4th Corridor Improvements Project- Phase 1 Intersection Improvements will signalize the intersection of NE 4th Street and Whitman Court NE, at Safeway and the Post Office.  The project will also build a westbound bicycle lane and sidewalk landscape strips.  The project will improve safety and traffic operations at this intersection and busy access to shopping and the Post Office.  Combined with this project is also the replacement of a water main under NE 4th Street.   

The Phase 1 project was advertised for construction in June of 2012, and was awarded on August 14, 2012 to Sanders General Construction LLC. The Contract amount is $2,129,217. Construction broke ground on August 23rd, completion is scheduled for April 2013. The Intersection Safety and Mobility Program will supplement the installation of signals at Whitman Avenue (2012) and Bremerton Avenue (future).

Construction Update (06/14/2013)
• The new traffic signal at NE 4th Street and Whitman Court NE has now been active for a month.
• All utilities on the north side of NE 4th Street are now underground, with the exception of the high voltage power transmission lines.
• All new concrete pavement, curb, gutter, and sidewalk has been poured. The sidewalk on the north side of NE 4th Street is pervious sidewalk designed to allow rainwater to infiltrate through the sidewalk.
• All new illumination poles have been installed.
• Landscaping has been planted.
• The project is considered complete, with only final punch list items being addressed by the contractor and related paperwork to close out the project.
• Special thanks to the U.S. Postal Service, Safeway, Taco Time, AutoZone and Seattle Bank for their cooperation and patience during this project.

The ultimate corridor improvements involve a series of improvements in this corridor to improve traffic operations such as rechannelization and traffic signal modifications, possible transit priority signal treatments and queue jumps.  This project will seek to meet pedestrian, transit and bicycle needs.

This ultimate corridor will follow the recommendations of the NE 3rd/4th Corridor Study, adopted in May 2005. The study refined the corridor transportation needs and costs, including pedestrians, transit users, bicyclists, and streetscape enhancement.  The estimate for design and construction for the entire corridor (from Sunset Boulevard to the east City Limits) is $40 million.
