Traveling on these roads during construction hours may delay your commute as crews work on trenching to install pipelines associated with the project.
Jamboree north segment: Work to lay pipeline on Jamboree Road north of Santiago Canyon Road began in November 2017 and was completed in early February 2018.
Jamboree south segment: Work to lay pipeline on Jamboree Road south of Santiago Canyon Road began in January 2018 and is expected to be completed in August 2018. Expect lane closures on portions of the road. During construction hours, at least one lane will remain open in each direction. During non-construction hours, two lanes will be open in each direction. For about three weeks beginning in April, the northbound dedicated bicycle lane will be closed between the Baker Pump Station and Canyon View Avenue during construction hours. During that time, a temporary combination lane (for bicycles and cars) will be provided. Otherwise, dedicated bicycle lanes on Jamboree will remain open. Also, a paved, off-road bikeway runs parallel to Jamboree (west side) and will remain available during construction.
