The El Camino Real Roadway Renewal Project will improve the function, access, and safety of El Camino Real while retaining the character of this critical corridor. The project area stretches 3 miles, between East Santa Inez Avenue and Millbrae Avenue and encompasses uniquely challenging pavement, vegetation, sidewalk, utility, drainage, and safety issues. This stretch of El Camino Real is also lined with heritage tree rows that are listed on the National Register of Historic Places and contribute to the unique character of the corridor.
Since 2017, Caltrans has been collaborating with the El Camino Real (ECR) Task Force through a series of meetings, field visits, and listening sessions. The result of this work was a suite of Task Force recommendations
that focused on four main areas of concern and two main objectives.
Also known as State Route 82 (SR-82), El Camino Real is owned and maintained by the California Department of Transportation (Caltrans). ECR handles nearly 30,000 vehicles daily. As a high-volume state route, it must comply with ADA accessibility regulations, visibility requirements, and safety guidelines.
1770s: Spanish expeditions establish El Camino Real (ECR) along routes used by Native Americans, linking missions, presidios, and pueblos from San Diego to San Francisco
1874: Local landowners hire landscape horticulturist John MacLaren to plant trees to line ECR: elms for shade and fast growing eucalyptus to shelter the slower-growing elms
1912: Paving of ECR begins
1930: Burlingame enacts the nation’s first zoning ordinances to protect tree rows on ECR from development
1985: Caltrans begins replacing historic trees lost to damage/disease
2008: Caltrans does extensive documentation of the Howard-Ralston Eucalyptus Tree Rows, including documenting size, type, and location of each tree
2012: The Howard-Ralston Eucalyptus Tree Rows are listed on the National Register of Historic Places
2017: ECR Task Force is formed and recommends options to deal with challenges along the roadway while preserving the tree rows
2019: Caltrans undertakes preliminary assessments for corridor deficiencies, including ADA upgrades, drainage improvements, and roadway restoration

Several challenges have developed as the roadway, sidewalks, infrastructure, and tree rows on El Camino Real continue to age.
ROADWAYPavement has exceeded its design life, evidenced by cracking and settlement. Subgrade settlement and pavement heaving from water damage and tree roots make superficial pothole repairs ineffective.
ADA ACCESSCurb ramps and pedestrian signal call buttons are missing at many intersections and existing ramps are not up to code. Uneven sidewalks are difficult to maintain and often unpassable for wheelchair users, strollers, and others with limited mobility or sight. Tree roots contribute to ongoing uplifting and cracking of concrete sidewalks.
DRAINAGESettlement and uneven pavement prevents water from draining properly, resulting in pooling and, in some cases, flooding. Older drain inlets are not all connected to the underground storm sewers. Some locations also have small pipes or clay pipes, which are easily clogged and difficult to clean.
VISIBILITYDense vegetation and large tree trunks prevent drivers turning onto ECR from seeing oncoming traffic and pedestrians. Vegetation can also block views for those who are maneuvering in and out of driveways.
POWER LINESWinter storms have led to damaged trees and downed power lines. PG&E does not recommend any trees be within 10 feet of power poles for safety.
TREE HEALTHAs trees age, the stability of their branches and roots becomes compromised. Many of the trees that make up the historic tree rows are nearly 150 years old and are approaching the end of their natural lifespan. Additionally, many have suffered damage from installation of utilities and curbs over the years. In some cases, tree roots have grown together over time, such that when one tree falls it destabilizes nearby trees.
With El Camino Real’s Roadway Renewal project, Caltrans is seeking to collaborate with the community to improve safety while preserving the corridor’s unique identity. We are working to develop a set of solutions that will:
We envision a street that is safe and beautiful for all who travel on it. Caltrans is ready to make the roadway improvements necessary to deliver an El Camino Real that the community will enjoy for decades. We look forward to continued involvement with all stakeholders, community groups, and residents as we create a streetscape that enhances the safety and livability of El Camino Real while maintaining its unique identity.Please stay tuned for more opportunities to provide feedback on our plans for this exciting roadway renewal project!
