Construction crews will continue work on the US 101 pavement rehabilitation project in Buellton as the project advances into another stage of construction.

Beginning Wednesday, Aug. 12, motorists will encounter changes to full time on and off ramp closures as crews begin reconstructing additional highway ramps.

The following ramps will be fully closed throughout the next stage:
· US 101 northbound on-ramp at State Route 246.
· US 101 northbound off-ramp at McMurry Road (Avenue of Flags).
· US 101 southbound off-ramp at State Route 246.
· US 101 southbound on-ramp at Avenue of Flags (Damassa Road).

The ramps should be reopened by early October 2026. The northbound McMurry Road on-ramp, and the north and southbound Santa Rosa on and off ramps will be reopened on Aug. 12.

Detour routes will direct motorists between State Route 246 and the McMurry Road/Avenue of Flags/Damassa Road interchange to either Avenue of Flags or McMurry Road to get onto US 101 while the ramps are closed.

Motorists are advised to follow posted detour signs and allow additional travel time while traveling through the work zone.

Current lane reductions on US 101 will remain in effect during this stage of construction. Motorists should anticipate travel delays, particularly during peak commute periods.
 
This work is part of a project to rehabilitate about 10 miles of US 101 through Buellton. Improvements include shoulder reconstruction, concrete pavement replacement, asphalt overlay, ramp reconstruction, drainage improvements, electrical upgrades, and guardrail improvements.
 
This project is expected to be completed by March. Contractor for this $30 million project is CalPortland Construction of Santa Maria.
