It’s almost here – the Mercer West Phase begins Monday, April 22nd, and here’s the roundup of what you need to know about traffic, lane restrictions, and Metro routes during this phase of construction. Some of these impacts are short-term, but some will last the duration of the Mercer West Phase through the summer of 2015.
Per SDOT: “Travelers can expect significant traffic and delays and should plan ahead and use alternate routes when possible.”
Lane Restrictions – SR 99/Aurora
Starting Monday, April 22, following the morning commute, crews will begin reducing SR 99 to two lanes in each direction between Aloha and Harrison streets to accommodate rebuilding the SR99/Aurora overpass as part of the Mercer West Phase.
These lane restrictions will remain in effect throughout the West Phase of the Mercer Corridor Project (estimated completion: Summer 2015):
