Construction Notices

Construction of the Mid-Coast Trolley extension project began in fall 2016. To find out more about the construction process, check out the Mid-Coast Trolley Extension Construction Info brochure in English and en Español.  

Current Activities

Ocean Beach Bike Path Closure: Pending weather conditions, the Ocean Beach Bike Path is scheduled to close March 29 through April 4, 2017, for San Diego River Bridge Double Track construction and ground improvements. Please follow signage to detour the bike path via Pacific Coast Highway and Taylor Street and use extra caution when traveling near the work area.

Morena Boulevard Construction Activities: Beginning in March 2017, Mid-Coast Trolley construction crews will start construction along Morena Boulevard from Clairemont Drive to Balboa Avenue. Initial activities will include traffic barrier installation, vegetation removal, utility installation, and wall construction for the future light rail infrastructure. To accommodate this work, the southbound lane of Morena Boulevard closest to the railroad tracks (the furthest west lane) will be closed to traffic for the duration of the project. Additionally, various portions of Morena Boulevard between Balboa Avenue and Tecolote Road may be reduced to one lane in either direction throughout the life of the project. Additional truck traffic should be anticipated during this work. Specific locations for lane reductions will vary as crews make progress on the new trolley line. Road conditions will change throughout the construction process and motorists, cyclists, and pedestrians should use extra caution when traveling near the work area and remain aware of travel speed and road conditions. Work hours are Monday through Friday, 7 a.m. to 5 p.m., although intermittent weekend work will sometimes be required. Traffic controls will remain in place 24 hours a day. View additional information on construction in this area.

Gilman Drive Bike Lane Near Rose Canyon Bike Path: A portion of the bike lane on Gilman Drive, below the I-5 freeway overpass, will be intermittently closed for project construction access. Cyclists will still be able to access the Rose Canyon Bike Path. Please exercise extra caution when traveling near the work area. View additional information.

Genesee Avenue Pedestrian Bridge Demolition: During one weekend in spring 2017 crews will demolish and permanently remove the pedestrian bridge at Executive Square and Genesee Avenue. A full road closure of Genesee Avenue from La Jolla Village Drive to Eastgate Mall will be required to complete this work. Traffic control signs, including necessary detours, will be posted. View additional information on this construction activity.

Genesee Avenue Road Widening: Work began in February 2017 to widen Genesee Avenue from Regents Road to La Jolla Village Drive. The work includes barrier installation, road re-striping, median and sidewalk demolition, and preparation to construct the viaduct - a bridge structure that will carry the trolley down the middle of Genesee Avenue. Several different traffic control phases involving lane closures and shifts will be ongoing as this work progresses. Traffic control signs, including necessary detours, will be posted. These types of traffic controls will be deployed at various times through early 2018. View additional information on this road widening.

Vegetation Removal along West Side of I-5: On January 30, 2017, crews began preparation work to remove trees and shrubs from the Caltrans right-of-way next to the southbound lanes of I-5 (the west side of the freeway from the La Jolla Village Drive off-ramp to the Nobel Drive off-ramp) in the future path of the trolley project. This work will require traffic controls, including installation of temporary barricades along the west side of southbound I-5. The vegetation removal work is anticipated to last approximately two months. Upon completion of all construction activities required in support of the Mid-Coast Trolley project in this location, vegetation will be planted. View additional information on this construction activity.

Marian Bear Memorial Park: In early January, crews began fencing off an area within the Rose Creek Channel, near the existing railroad tracks, for construction activities and staging equipment purposes. There will be no access along the Rose Creek channel between Marian Bear Memorial Park and Rose Creek open space. Please be aware of detour signs.

Gilman Drive Bridge: Work began in late 2016 on I-5 near Gilman Drive to prepare for construction of the Gilman Drive Bridge. Crews have installed temporary barricades near Gilman Drive that will remain for approximately two years. The new bridge will connect the west and east sides of UC San Diego and span I-5. View additional information on preparation for and construction of the Gilman Drive Bridge.

Friars Road: In fall 2016, crews began work along Friars Road between Sea World Drive and Napa Street to build the San Diego River Bridge Double Track project in advance of construction on the Mid Coast Trolley project. Several traffic control phases involving multiple lane closures and shifts will be implemented in this area throughout the course of the project to help facilitate this work. The concrete barrier railing that has been placed on Friars Road is to support both projects and also is expected to last throughout the project duration. View construction notice.

Balboa Avenue: Crews continue to work nights to minimize impacts to local traffic. For all residents and businesses in the area, access to driveways will be maintained throughout the project. There may be some portions of roads closed or detoured at night. View information on work occurring on Balboa Avenue.

Santa Fe Street: Crews are working day and night shifts to complete a water line installation. Traffic controls are currently in place. SDG&E began on a separate utility relocation project in the same area in June 2016 and will continue through winter 2016.

Genesee Avenue: Day work is ongoing at the intersection of Eastgate Mall, progressing north to Regents Road. Night work hours will be in effect, and some lane closures will be necessary to complete this utility work. View information on work occurring on Genesee Avenue.

Interim Bike Path: Crews have constructed an interim bike path to reroute bicycle traffic around work zones. The existing Rose Canyon Bike Path will be temporarily closed during construction of the Trolley extension. The interim bike path opened in June 2016. View more information.
