Temporary One-way Traffic Flow on East Cliff Drive to Begin November 20th

It has been a goal since the project began to maintain two lane, two way traffic on East Cliff Drive between 5th Avenue and 7th Avenue to the maximum extent feasible during construction. When Graniterock shifted the two lanes to the north side of the road to begin work on the coastal protection structure, and installed safety barriers and chain link fencing to protect vehicles from getting too close to the excavation, the lane width was narrowed as much as possible to allow construction to proceed. While the lane width is within the legal limit, we have received reports of vehicles experiencing difficulty traversing the curve south of the 7th Avenue intersection. Larger vehicles, such as buses, delivery trucks, and trucks with trailers, experience the most difficulty.

In order to facilitate safe traffic flow around the curve, the traffic pattern will be temporarily modified to allow eastbound traffic only on East Cliff Drive between 5th Avenue and 7th Avenue, beginning Monday, November 20, 2017.

Westbound traffic will be routed north on 7th Avenue, west on Eaton Street, and south on Lake Avenue back down to East Cliff Drive. Since the start of the project, it was known that at some point, one lane traffic would become necessary to complete construction, but it was hoped that it would not be until later on. Two travel lanes will be restored at such time as both traffic and construction can be safely accommodated and no later than project completion, scheduled for April 27, 2018, weather permitting.

Coastal Protection Structure

Sheet pile work has been completed and Graniterock has begun pouring the controlled low strength material (CLSM) that makes up the bulk of the structure. The CLSM will be poured in two foot lifts across the entire structure. Graniterock estimates it will take fourteen to fifteen working days to pour all of the CLSM, which will bring us to Thanksgiving, and maybe a couple of days after. Once all the CLSM has been poured, work will begin on the footing in front of the wall, and the reinforced shotcrete that covers the surface of the structure.


Parking within the construction zone is permitted only in the four stall parking area on the north side of East Cliff Drive between 5th Avenue and 6th Avenue. Please observe all construction area signage.

All parking in the Twin Lakes area is included in the Live Oak Parking Program. Please visit http://www.dpw.co.santa-cruz.ca.us/Home/ParkingPrograms.aspx for more information about the program.

General Project Information

All Harbor restaurants, stores, businesses, and facilities are open during construction.

Twin Lakes Beach and the Harbor area are destinations for visitors throughout the year, and in all kinds of weather. For everyone’s safety, please use caution when moving through the construction zone, obey all signage, and please share the road.

We appreciate the public’s patience during the construction process and look forward to the completion of the improvements in spring of 2018. The completion date is subject to change due to weather or other conditions.
