SDOT advises travelers of the cancelation of the August 26 – 29 weekend closure of the I-5 on- and off-ramps at Mercer St. as part of the Mercer Corridor Project. This cancelation is being made in order to accommodate the many nearby events taking place this weekend which are expected to draw large crowds.

The next confirmed full weekend closure of the I-5 on- and off-ramps at Mercer St. will be:

• September 9 – 12.

Closure hours are scheduled for Friday at 11:00 p.m. to Monday at 5:00 a.m. Additional full weekend closures for fall 2011 will be announced—further notification will be provided as dates are finalized.

Detour route maps are available on the project website at: Detour routes shown will be signed on roadways and may be heavily used, particularly Denny Way both eastbound and westbound.

During these closures, the I-5 on-ramp at University St. will be concurrently closed to provide more efficient traffic flow around the closed Mercer St. exit lane.
