    street and adjusting utilities between Western Avenue and Sixth Avenue.  The base repair will occur during the night shift, 6:00 PM to 6:00 AM, September 14-17.

The Seattle Department of Transportation (SDOT) is making improvements to several arterials in Downtown Seattle in 2009. The projects are funded by the “Bridging the Gap” transportation levy approved by Seattle voters in November 2006.

SDOT is planning to make improvements to Marion Street, between Western Avenue and Sixth Avenue, starting in late July or early August 2009. The project is expected to be completed by early October 2009.

Project Description

The project will include new concrete and asphalt pavement, upgraded curb ramps, and some areas of replaced sidewalk. 

Originally scheduled for 2010 construction, this project was accelerated as part of the Mayor's economic stimulus package, called "Seattle Jobs Forward", to create jobs and revive the local economy. The "Seattle Jobs Forward" is a package of immediate local action to create direct jobs and boost Seattle’s economy over the next two years.
