Coastside County System Alternative 1 Route Map

Alternative 1 Key Changes

Route 112 would be shortened to operate between Sharp Park and Serramonte. It would operate every 30 minutes on weekdays instead of hourly. Route 110 service would improve to every 30 minutes seven days a week.

Route 118 would run between Pacifica and Colma BART instead of continuing on to Daly City BART to be more reliable.

Route 294 would no longer serve College of San Mateo due to low ridership and would operate hourly during midday on weekdays instead of every two hours.

Coastside County System Alternative 2 Route Map

Alternative 2 Key Changes

Route 112 would be shortened to operate between Sharp Park and Colma BART.

Two routes would serve the growing employment areas in Oyster Point.

Route 294 would no longer serve College of San Mateo due to low ridership, providing a faster trip for those traveling between the Bay and the Coastside.

Coastside County System Alternative 3 Route Map

Alternative 3 Key Changes

Route 112 would be deleted. Route 110 frequency would improve to every 30 minutes seven days a week. Riders wishing to travel to Serramonte or Colma BART would need to transfer.

Route 294 would improve midday weekday frequency to every 60 minutes, up from every 120 minutes.

A new on-demand service in Half Moon Bay would be implemented. A ride on a smaller vehicle, which could be reserved with a phone call or via an app, would provide service anywhere within the zone.

Route 17 | Linda Mar Park & Ride - Miramontes/Moonridge (Half Moon Bay) - Pescadero

Existing Service

Route 17 is a below average productivity route that provides coverage to lower-density areas along the Coast between Pacifica and Half Moon Bay. Pescadero, south of Half Moon Bay, gets limited service to provide lifeline connections from that community. Weekend service is only every two hours. Higher frequency service was a top request during public outreach.

Possible Changes

Route 17 Alternatives

Alt 1: Direct, high-frequency service within the county

This option simplifies the route to operate with fewer deviations off US Highway 1. Route deviations with lower ridership would be removed, including Sunshine Valley Road, 6th Street, Seton Coastside Medical Center, Cañada Cove, and the extension to Pescadero. Riders from 6th Street, Seton Coastside Medical Center, and Cañada Cove would still be able to access Route 17 with a longer walk. Riders in Pescadero would be able to use SamCoast service. School service on Route 18 would not change.
Resources saved by reducing deviations on Route 17 would be reinvested in better weekend service. With the deviations removed, Route 17 would operate every 60 minutes on Saturdays and Sundays.

Alt 2: Improved connections to rail and the region

The existing route would continue to operate with no changes.

Alt 3: Retain geographic coverage

No changes to Route 17 are made in this alternative. A new on-demand service in Half Moon Bay would supplement Route 17 service.

Route 110 | Linda Mar Park & Ride - Daly City BART

Existing Service

Route 110 has average productivity. Ridership is focused to Daly City in the morning and from Daly City in the afternoon. There are some school-day-only trips woven into the schedule. Public input included requests for earlier service and more frequent service on weekends.

Possible Changes

Route 110 Alternatives

Alt 1: Direct, high-frequency service within the county

To improve travel times for the majority of riders, this option removes the route deviation from Skyline Drive to serve Longview Drive. Affected riders would need to walk up to five minutes to a stop on Skyline Drive.
Route 110 would operate more often, every 30 minutes, during the midday on weekdays and weekends.
All Route 110 trips that operate only on school days would be renamed as Route 10.

Alt 2: Improved connections to rail and the region

This alternative is the same as Alternative 1, except that it would run as often as the existing service, every 60 minutes during the midday on weekdays and weekends.

Alt 3: Retain geographic coverage

Route 110 would operate more often, every 30 minutes, during the midday on weekdays and weekends.
All Route 110 trips that operate only on school days would be renamed as Route 10.

Route 112 | Linda Mar Park & Ride - Colma BART

Existing Service

Route 112 is a below average route in terms of ridership. It serves a small, unique market that mostly overlaps with other routes. Public input included requests for better connectivity to other routes and earlier service.

Possible Changes

Route 112 Alternatives

Alt 1: Direct, high-frequency service within the county

This option includes several recommendations to reduce duplication with other routes and to improve frequency.
In this option, Route 112 would end at Serramonte. Routes 120, 121, and 130 would continue to provide service between Colma BART and Serramonte. Likewise, the southern end of the route would be Sharp Park and the route would not continue to Linda Mar. Route 110, which would have improved midday and weekend service, would continue to serve Linda Mar and Sharp Park.
Frequency on Route 112 would increase to every 30 minutes, seven days a week.
All Route 112 trips that operate only on school days would be renamed as Route 12.

Alt 2: Improved connections to rail and the region

To reduce duplicating service with Route 110, Route 112 would end at Sharp Park and would not continue to Linda Mar. Route 110 would continue to serve the Linda Mar Park-and-Ride and Sharp Park.
This recommendation is made in conjunction with operating more frequent service during rush hours on Route 118 connecting Linda Mar to BART.
All Route 112 trips that operate only on school days would be renamed as Route 12.

Alt 3: Retain geographic coverage

This option discontinues Route 112 due to lower ridership and duplicating service on many other routes. Most existing passengers would still have access to Routes 110, 121, or 130, but would have to transfer to reach their destination. Existing riders on Gateway Drive would need to walk about five to ten minutes to a bus stop on Skyline Drive (Route 110) or Hickey Boulevard (Route 121).

Route 118 | Linda Mar Park & Ride - Daly City BART

Existing Service

Route 118 provides peak directional limited stop service from Linda Mar and Pacifica to two BART stations. Public input included requests for earlier service and better schedule coordination with other routes.

Possible Changes

Route 118 Alternatives

Alt 1: Direct, high-frequency service within the county

In this option, Route 118 would end at the Colma BART station and no longer serve Daly City. Route ECR and BART would continue to provide service between Daly City and Colma BART. This recommendation would improve the reliability of Route 118, as it is frequently delayed on the streets between the two BART stations.

Alt 2: Improved connections to rail and the region

To improve reliability and provide a faster trip to Daly City, Route 118 would no longer serve the Colma BART Station. Passengers wishing to travel to Colma could transfer to BART or Route ECR.
Route 118 would have improved frequency with trips every 30 minutes during the morning and evening peak periods.

Alt 3: Retain geographic coverage

The existing route would continue to operate with no changes.

Route 294 | San Mateo Medical Center – Main/Poplar (Half Moon Bay)

Existing Service

Route 294 connects Half Moon Bay to San Mateo but has below average ridership. Public input included requests for more frequent and later service to Half Moon Bay.

Possible Changes

Route 294 Alternatives

Alt 1: Direct, high-frequency service within the county

In this option, Route 294 would continue to serve all stops in Half Moon Bay and connect to the Hillsdale area in San Mateo. Due to low ridership, deviations to College of San Mateo and San Mateo Medical Center would be discontinued. The route would also be modified to serve the new Hillsdale Caltrain station location. The bus would run more often, every 60 minutes all day on weekdays and on weekends.
Riders could continue to access the College of San Mateo with a transfer to Route 250. Riders to San Mateo Medical Center could transfer to Route 295 or walk about five minutes.

Alt 2: Improved connections to rail and the region

This alternative is the same as Alternative 1, except that it would only run every 120 minutes during midday and evenings on weekdays, which is the same as the existing service.
Riders could continue to access the College of San Mateo with a transfer to Route 250. Riders to San Mateo Medical Center could transfer to Route 295 or walk five minutes.

Alt 3: Retain geographic coverage

In this alternative, Route 294 would continue to serve the College of San Mateo but the deviation to San Mateo Medical Center would be discontinued.
Between College of San Mateo and the Hillsdale Caltrain Station, Route 294 would travel on 28th Avenue. Riders on Alameda de las Pulgas would still have access to Route 250.
Frequency on weekends and during the midday on weekdays would be improved to every 60 minutes.

HMB-OD| Half Moon Bay On-Demand Service (NEW!)

Possible Changes

Half Moon Bay is a rural area with limited road access that has historically been hard to serve well with regularly scheduled bus service. An on-demand zone serving Half Moon Bay would help connect people to grocery stores, community services and Route 294 with service to other parts of San Mateo County. The mid-Coastside on-demand transit service would operate from 8:00 a.m. to 5:00 p.m. seven days a week.
