A project to reconstruct the bridges on Highway 101 at the interchange with State Route 135 in Los Alamos will continue with the demolition of the northbound bridge beginning Tuesday, Sept. 6.
This roadwork will result in a 24-hour closure of State Route 135 between Bell/Main Street to San Antonio Boulevard, 7 a.m. Sept. 6 to 7 a.m. Sept. Sept. 7.

A temporary shuttle service will transport passengers near Los Alamos Rancho Mobile Home Park and Los Alamos Senior Center. U.S. 101 will remain open in both directions.
Access to the southbound 101 on- and off-ramps will remain open and the northbound on- and off-ramps at S.R. 135 will remain open for travelers to the Skyview Hotel and Peppertree Lane.
In addition, travelers on northbound Hwy. 101 will encounter a traffic switch onto a newly constructed bridge in the center median beginning Wednesday morning, Aug. 31 for the next four months while construction proceeds on new traffic lanes.
The project will continue to include periodic intermittent full overnight closures of S.R. 135. Traffic delays are not expected to exceed 15 minutes.
Electronic message boards and detour signs will be posted to advise travelers about the closure. Contractor for the $10 million project is CalPortland Construction of Santa Maria. It is scheduled to be complete by March 2023.
