Drivers may want to plan ahead for the upcoming I-5 on- and off-ramp closures at Mercer Street, tentatively planned for the weekend of January 6-9, weather permitting. The ramps will close at 11 p.m. on Friday, January 6 and will remain closed until 5 a.m. on Monday, January 9. The closures are needed to prepare for the next stage of the Mercer East Project when traffic is switched to newly constructed lanes and work begins in the old lanes.

Traffic Switch Begins January 9;

Boren, Terry and Westlake will be Closed at Republican

Starting Monday, January 9, “Stage 2” of the Mercer East Project begins. Traffic on Mercer Street will switch to the three new lanes just to the north of the existing lanes. The new lanes will continue to provide access to the I-5 on-ramps and to Fairview Avenue N.  At the same time, Boren, Terry, and Westlake avenues will be open only to local access traffic between Mercer, and Republican streets, and through traffic coming from the south will need to take an alternate route to reach Mercer Street such as Ninth Avenue or Dexter Avenue. Closure of these streets (Boren, Terry and Westlake) at Mercer is necessary in order for the contractor to complete work in the area of the old lanes on Mercer Street. 

SDOT will continue to provide updates of the work schedule and detour maps as the date approaches.
