Project Description/Scope


The project proposes to widen southbound (SB) State Route 17 (SR-17) from 3 lanes to 4 lanes, eliminating the forced merge of vehicles from SR-1 NB#1 lane with SR-17 SB #2 lane. Shoulders will be widened on SR-17, both north and south of the 1/17 separation. Concrete barrier will be installed, drainage improved, and highway lighting relocated.

Sideswipe and rear-end collisions are occurring at merging locations at each end of this highway segment. The accident rate at this location is currently twice the statewide average for similar facilities.

SANTA CRUZ COUNTY–A project to resurface and widen the shoulders of Highway 1/17 in Santa Cruz County resumed on Monday night, Jan. 25.

Phase 1 will last about two months and will include the following closures:
The northbound Hwy. 1 loop ramp (Fishhook) has been reduced to one lane and is subject to full closures Monday through Friday from 8:00 pm until 5:30 am. Residents can expect considerable noise, depending on the roadwork being performed. Motorists may detour onto Pasatiempo Drive. Southbound Hwy. 17 will to be reduced to one lane Monday through Friday from 8 pm until 5:30 am.

Phase 2 will last about two months and will include the following closures:
Southbound Hwy. 17 will be reduced to one lane Monday through Friday from 10 pm until 5:30 am. The northbound Hwy. 1 ramp (Fishhook) will be subject to lane and full closures Monday through Friday from 8:00 pm until 5:30 am. Motorists may detour onto Pasatiempo Drive.

As currently planned, this week includes tree removal, saw-cutting and excavation work. The following two weeks will consist of working overnight on the barriers in front of all the bridge columns, which is all labor and will not be loud; day work will consist of underground work and electrical work. All work will depend on the weather and roadway surface conditions.

Motorists can expect delays not to exceed 15-20 minutes. This project, when completed in the spring, will create two dedicated lanes on northbound Hwy. 1 from the Fishhook. The contractor for this $1.2 million project is Granite Construction of Santa Clara, CA.

Caltrans reminds motorists to move over and slow down when driving through highway construction zones.
