Anticipated Construction Schedule for Two-way Mercer

Due to the magnitude and complexity of this project, as well as the volume of traffic that will be managed during construction, the City developed construction staging plans to reduce impacts to users of the corridor and keeps people and goods moving.

Stage 1 (fall 2010 to fall 2011)
Install 9th Ave. N sewer replacement and restore roadway
Construct westbound Mercer St. lanes construct new westbound lanes along the north side of existing Mercer Street.
Construct from new westbound lanes to Broad St.
Begin I-5 ramp realignment and utility work on Fairview Ave. N

Stage 2 (fall 2011 to fall 2012)
Reroute Mercer St. traffic to new lanes
Reconstruct existing Mercer St. and portion of Fairview Ave. N

Stages 3 & 4 (fall 2012 to summer 2013)
Construct Valley Street improvements
Construct Westlake Avenue North improvements
Complete construction of Fairview Avenue North improvements to the north of Mercer Street*
Construct Roy Street improvements**

* Some utility work may occur in this area during Stage 1
** Work may be shifted to Stage 1 or Stage 2
Schedules are estimated and dependent on weather condition and availability of materials.
