WHAT:

Crews are expected to reconstruct the northbound SR-55 Dyer Road loop on-ramp, which will require an extended closure of the ramp.

WHEN:

The on-ramp is expected to close as soon as 9 p.m., Friday, Oct. 24 and reopen to motorists by 5 a.m., Sunday, Nov. 23.

This work may be loud. The schedule is subject to change due to inclement weather or unforeseen operational issues.

Crews continue to conduct efforts to keep the project corridor clean, including the removal of weeds, as well as ensure local streets are maintained for pedestrians and motorists. In addition, regular site inspections and sweeps along the mainline are performed.  

Please report graffiti, trash, and damaged items along the corridor to the Outreach Team at 888-371-2555 or email SR55Info@octa.net.

OCTA, in cooperation with Caltrans, is improving 4 miles of SR-55 between I-405 and I-5. The project will improve traffic flow and reduce travel time by adding one regular lane and one carpool lane in each direction. Also, the project will add merge lanes between several interchanges and stripe carpool lanes for continuous access, augmenting safety on the freeway by making merging easier. These enhancements are expected to create a better, smoother driving experience for motorists.
