Draft US 101North County Multimodal Corridor Strategy:

Comment on the draft strategy by September 19, 2025

Draft US 101 North County Multimodal Corridor Strategy

The TA is accepting comments from August 18 to September 19, 2025.

The San Mateo County Transportation Authority (TA) has prepared the draft US 101 North County Multimodal Strategy which identifies projects that best meet the needs for all types of transportation options. The North County project corridor includes the area from the San Francisco and San Mateo County line to the north and approximately one mile south of the I-380 interchange and includes a one-mile buffer along US 101. This includes the cities of Brisbane, Millbrae, San Bruno, South San Francisco, and unincorporated areas of San Mateo County.

Below, you can view the draft US 101 North County Multimodal Strategy and provide input. This strategy aims to improve the way people and goods move through the North County corridor. It includes an introduction to the 101 Corridor Connect program, analysis of existing conditions, summary of the stakeholder and community outreach that was conducted, project identification and scoring methodology, and the final list of priority projects for North County.

Suggestion
Strongly support.
Suggestion
Ensure strong connectivity with the BART station including bike markings, push buttons and signage.
Suggestion
Similar to SSF and Millbrae, bike lanes are definitely possible here and I would not want these to come at the expense of bus-only lanes. I believe we can have both and make the case that parking is less important, but it will require significant public outreach.
Suggestion
This is sorely needed. Please ensure that the additions are not just post but concrete separated for extra protection. Ensure that this connects fully with the Bay Trail. The connectivity on the east side of 101 is especially poor and dangerous for cyclists.
Suggestion
Yes, this would be great! Please do not forget to include bike routes in your wayfinding funding. A number of cities including Berkeley and Oakland have good examples that show destination and approximate time.
Suggestion
Similar to the Millbrae example, this needs Class IV bike lanes called out. They are already included in the SHOPP project and have support from Caltrans staff and SSF and include parking removal.
Suggestion
Daly City is working on their portion of Geneva, unfortunately without any consideration for a road diet even though they have the road width. I generally do not support Class II bike lanes - in most situations they are not safe or comfortable for less confident riders. Strongly encourage upgrading to Class IV or considering a two way cycletrack if this is possible on this corridor.
Suggestion
SMCTA and Caltrans can definitely add protected bike lanes to this corridor, I strongly suspect it has excess capacity, and it is sorely needed. With major development in the Caltrain Mulitmodal station area (including SMCTA's new headquarters), bike accessibility must have equal footing with ped and bus improvements.
Suggestion
The challenge I see with breaking up the ECR segments by city is that the SHOPP project areas usually cross jurisdictions. For example, San Bruno/Millbrae SHOPP is combined. Establishing a working group between Colma, SSF, SB, Millbrae and Caltrans would help get folks on the same page. Much of this corridor has min 6 through lanes, often with multiple turn pockets at major intersections, and up to 120 ROW. Call for road diets along the corridor and work with Caltrans early in the process to secure the traffic analysis and ensure funding to get the multimodal improvements you are seeking. If this can't be achieved through Caltrans' SHOPP timleine, lead a process with cities to secure funding to supplement SHOPP or pursue independent work.
Suggestion
+ 1 to comment next to mine.
Question
Why just 1 mile? There are likely plans that contain key connections that would be relevant to this work, such as San Bruno's Transit Corridor Plan. That plan boundary is likely about a mile away on San Bruno Avenue.
Suggestion
In the future, I think it's worth finding some higher-turnout events that will create the foot traffic desired for this style of engagement (which I definitely support!). Please consult with local staff who would have more data. Maybe even go for two events per community.
More bike lanes on ECR like Palo Alto please
Please connect Caltrain to the airport or connect bart further down 101 so we can better get to the airport via train. This will alleviate congestion
Suggestion
consider protecting bicycle lane and working with Burlingame for future plans to improve connectivity to existing class IV lanes that start at broadway.
Suggestion
current bike path to connect to the bike trail also needs repaving
Interesting data on SamTrans buses. Show while many people overlook these users really need this service and have fewer alternatives.
Suggestion
Need to focus on safe ways to cross 101 by bicycle and working to eliminate this barrier. Bike lanes or multi use paths on either side are of limited use without safe methods to cross 101. Also any way to focus traffic to distributor type streets and reduce traffic level and speeds on neighborhood type streets. Saw a lot of the how this works in the Netherlands. Make local neighborhood streets slow speed and safe for bikes instead of bike lanes on busy streets and focus on safe crossings.
Suggestion
consider continuing this to oyster point boulevard for connectivity
Suggestion
considering improving bike lane to class IV
Suggestion
difficult to cross El Camino from caltrain station to Samtrans ECR route
Suggestion
Please connect to Brisbane
Suggestion
Improving ped/bike access to Caltrain at Millbrae will also inadvertently improve access to BART and the airport!! This is a WIN/WIN/WIN in my book.
Suggestion
THANK YOU! The bay trail is amazing and I brag about to visitors. I hate having to explain that there are gaps.
Suggestion
Yes! I love improvements to ECR for pedestrians and transit! Would it be possible to also include bike lane improvements for this project?
Suggestion
The Millbrae station is very confusing the first time you visit. Many people get confused on which train to hop on when connecting to the airport. Maybe putting signs on the trains that say "Yes. This train is going to the airport for its next stop." Because many of the trains just say the final destination, it is often not clear that it will go to the airport.
Suggestion
Yes! I love improvements to ECR for pedestrians and transit! Would it be possible to also include bike lane improvements for this project?

Suggestion
This helps with connectivity across Caltrain but not across 101. I think connectivity should have scored lower.
Suggestion
I'm not understanding how this scored worse than the northern airport segment regarding sustainability.
Suggestion
Connectivity should score higher, as the existing north/south connectivity is very poor between San Bruno and South San Francisco. The northern airport segment actually has bike lanes (with gaps) and doesn't provide as much benefit
Question
Will this connect to Rollins Rd?
Suggestion
Can the existing paths and trails such as the one near Bayside Manor Park, along California Dr south of Trousdale, and between Hemlock and Sierra Ave (north of Millbrae Bart) be opened and accessible for people walking and biking?
Suggestion
For the cost, this provides little benefit to people walking or biking. Alternatively, a better connection between the Centennial Way Trail and Bay Trail would provide a huge benefit for a more attainable cost.
Suggestion
Converting existing lanes makes sense... adding additional lanes makes less sense. The existing capacity seems to be limited to the very short weaving segment between the Produce Ave (southbound) onramp and the 380 WB ramp.
Suggestion
Many people biking use a short segment of ECR to connect through from Hemlock.
Suggestion
Can Commute.org provide these shuttles?
Suggestion
In Rollins Ave part of the plan south of this location? Improvements in mid-county should include this segment as a priority.
Suggestion
There are not any good connections between Millbrae and South San Francisco. This is a designated bike route, and it's terrifying. The other connections, like S. Linden, have fewer vehicle and less traffic, and connect better to the other north/south corridors like Huntington and Rollins.
Suggestion
Should this project not complete and improve the connection to Daly City on Hillside? Then, there is a continuous route from BART to the Ferry.
Suggestion
Wayfinding and signage, along with gap closures and quick build improvements can be added now for significantly less.
Suggestion
This path should help create a better connection at Southline for people headed toward the Bay Trail. The connection at Tanforan is too narrow, and doesn't connect well to the future bike facility there.
Suggestion
I'm not sure a new signal is the right solution. Consider spending this money on improving the bike lane connection to Brisbane, which has several terrifying gaps.
Suggestion
Start at Oyster Point.
Suggestion
South Airport has been a key bike route for many years with very little investment for people walking or riding their bikes.
Suggestion
S. Linden is more heavily used as a north/south route due to the alignment with the new Huntington cycle track. Until S. Airport is completed, some immediate changes could be made here to support biking.
Suggestion
I feel that this segment would provide a big benefit to multiple types of users.
Suggestion
Consider extending a few hundred feet north to Oyster Point Blvd / Sister Cities Blvd, which is a natural transition point.
Suggestion
I'd rather go a bit out of the way for a safer experience. Consider swapping Connectivity and Safety.
