CLOSURE OF SOUTHBOUND HIGHWAY 1 ON-RAMP
AT PARK AVE. BEGINS APRIL 19

SANTA CRUZ COUNTY — A project to construct north and southbound auxiliary lanes and bus-on-shoulder improvements on Highway 1 between the Bay Avenue/Porter Street and State Park Drive interchanges continues this week.

On Sunday, April 19, crews will close the southbound Highway 1 onramp at Park Ave. The southbound Park Ave. onramp is scheduled to be closed for approximately six months. This is because the southbound section involves a more extensive scope of work which includes a full roadway structural replacement.

Travelers will have two detour options. One detour will be heading south on Soquel Dr. and the other will be south on McGregor Dr. where both roads lead to the southbound Highway 1 State Park Dr. onramp.

During the closure, crews will be making necessary improvements to the onramp to accommodate the bus-on-shoulder facilities.

Message and directional signs will alert travelers in advance of the areas under traffic control. Please allow for extra time for your travels through the area.
