Manor Drive Overcrossing Improvement Project


Preliminary Planning Study

Upcoming Meetings

None at this time.

Past Community Meeting Presentations and Meeting Notes:



The existing Manor Drive overcrossing was constructed in 1963. The overcrossing lacks shoulders and has narrow lanes and tight turning radii that require buses and large trucks to cross the center line into opposing traffic lanes to negotiate right and left turns. The sidewalks and guardrails show evidence of multiple sideswipes, most likely by buses and trucks. The existing ADA ramps at the intersections are narrow and steep that some wheelchair-bound individuals have reportedly fallen out of their wheelchairs while using the ramps. The existing ADA ramps do not meet ADA requirements and need to be upgraded to current design standards. Manor Drive, Oceana Boulevard, and Palmetto Avenue all lack formal bicycle facilities. Cyclists must share vehicle lanes to reach destinations in the project area or to connect with existing Class I bikeways on Esplanade Avenue to the west or the Milagra Ridge open space, part of the Golden Gate National Recreation Area, to the east.


Project Overview

The Highway 1/Manor Drive Overcrossing Improvement Project would widen the highway overcrossing at Manor Drive between Palmetto Avenue and Oceana Boulevard to better accommodate buses and trucks. The project will construct new Americans with Disabilities Act (ADA)-compliant ramps, install traffic signals with pedestrian signal heads, and construct better[1]defined crosswalks for the increased protection of pedestrians and bicyclists. This preliminary planning study will also evaluate the construction of a new freeway on-ramp for northbound Highway 1 at Milagra Drive and Oceana Boulevard, utilizing the existing bus pull-out on-ramp that is no longer in use. This will allow local traffic to access northbound Highway 1 without traveling through the Manor Drive/Oceana Boulevard intersection and therefore reduce congestion at the Manor Drive overcrossing and along Oceana Boulevard.



The proposed project schedule is as follows. The schedule is subject to change based on environmental impacts, cost, and funding availability.
