WSDOT - I-5 - 2nd Street Bridge Replacement - March 2006 Quarterly Project Report

I-5 - 2nd Street Bridge Replacement - Complete September 2006
*Quarterly Project Report Update for Quarter Ending March 2006*

Project Title & Location I-5/Second Street Bridge - Replace Bridge - Mount Vernon	Project Description This project replaces a low-clearance bridge over I-5, eliminating a through-city detour now required for over-height trucks. The new bridge eliminates the risk of over-height trucks hitting the bridge over busy I-5 and will meet seismic standards.
Contractor/Consultant Project was awarded to Mowat Construction on June 1 for 2% over engineers estimate.
Recent Progress Tuesday October 18, 2005 we opened the new 2nd street bridge to traffic. SR536 work completed includes first lift of asphalt, drainage, and curb and sidewalk. The remaining work on SR536 includes final lift of asphalt and striping, this work will be completed summer 2006. The parking lots are reconstructed and ready for use. The slope on the east side of I-5 have been graded and permanent slope erosion protection installed.
Design Construction Impacts Work to remove and replace the cast-in-place barrier and paving of southbound I-5 in the vicinity of the new bridge will begin in August. This work will require a lane closure of northbound and southbound I-5 at night. This work will also include drainage improvements and reconstruction of the northbound I-5 right shoulder .
Environmental Impacts / Compliance The City of Mount Vernon discovered buried fuel tank on County R/W in a parking lot that was being overlaid as part of this project. The tank was removed and environmental issues addressed. No other issues at this time.	Impacts to Traffic Traffic will be detoured through Mount Vernon at night when full directional closure of I-5 is required (Contractor has used 11 of the 23, I-5 closures allowed in the contract). Mitigation efforts include a comprehensive public awareness campaign. The next I-5 closures will occur this spring to remove and replace median barrier, construct new drainage, and pave south bound I-5 in the vicinity of the new bridge.
