Regional Projects


The Regional Transportation Commission (RTC) is responsible for regional projects funded by Measure D. Click a tab to see specific project plans for the next five years, as approved by the Regional Transportation Commission. The RTC updates the 5-year plans each June, following a public hearing  (with interim amendments to the RTC budget and 5-year plans made when needed). Annual expenditure reports and audits are provided on the Oversight page.

June 6, 2019 – Following consideration of public input, the RTC adopted the updated Measure D 5-Year program of projects for the regional and RTC oversight projects – Highway Corridor, Active Transportation/Trail Program, Rail Corridor, San Lorenzo Valley/Highway 9 Corridor, and the Highway 17 Wildlife Crossing, as well as the 5-year program of projects for Community Bridges-Lift Line.

Measure D will provide approximately $125,000,000 in funding to improve safety and traffic flow, fund car-free highway overcrossings, and other safety programs.

On Highway 1, extending three mid-county on-ramps to create full merge lanes down to Aptos (State Park Drive) between exits would allow more time for motorists to merge and exit safely.

Measure D will provide an estimated $97,000,000 to leverage grants for auxiliary merge lanes between:

  • Soquel Drive and 41st Avenue
  • Bay Ave/Porter St and Park Avenue
  • Park Avenue and State Park Drive
  • State Park Drive and Rio Del Mar
  • Rio Del Mar and Freedom Blvd

Improving the traffic flow and safety of merging on Highway 1 would benefit:

  • Mid- and south-county commuters with commutes too long to bike or walk
  • Response times for medical, fire and law enforcement
  • Bus riders on cross-county routes
  • Neighborhoods which currently experience cut-through traffic during commute times

Measure D will also provide an estimated $7,000,000 for 2 new bicycle and pedestrian bridges over Highway 1

  • In Live Oak at Chanticleer Avenue
  • In Seacliff/Aptos at Mar Vista Drive

Other safety and system efficiency programs will receive an estimated $21,000,000, including:

  • Cruz 511 County traveler information service
  • Safe on 17: law enforcement, drainage, warning devices, tree trimming and other safety efforts on Highway 17
  • Freeway Service Patrol tow trucks helping disabled vehicles and removing debris from Highway 1 and Highway 17

The Monterey Bay Sanctuary Scenic Trail / Coastal Rail Trail will be a paved bicycle and pedestrian pathway to be built within the 32-mile Santa Cruz Branch Rail Line corridor. The rail trail forms the spine of the 50-mile Monterey Bay Sanctuary Scenic Trail Network.  Additional trail projects will connect the rail trail to key destinations and activity centers.

This level, car-free transportation alternative will provide kids, commuters and recreational bicyclists and walkers a safe and enjoyable way to travel.

Measure D would provide an estimated additional $85,000,000 towards the Coastal Rail Trail, including:

  • Construction of bicycle and pedestrian trail sections connecting Santa Cruz, Capitola, Aptos, and Watsonville
  • New bike and pedestrian bridges
  • Adding lighting and security features
  • Keeping the trail safe and clean for active use
  • Storm and drainage management
  • Leveraging matching state and federal grants for full Coastal Rail Trail network completion

The first four segments  of the rail trail – on the North Coast, in the City of Santa Cruz, in Live Oak, and in the City of Watsonville, will result in close to 13 miles of trails that will be at least 12 to 16 feet wide. The first segment begins construction in 2018.

After many years of diligent work and negotiations, the SCCRTC purchased the Santa Cruz Branch Rail Line to expand transportation options and alternatives to driving, and plan for future mobility needs. Uses of this continuous transportation corridor could include:

  • Transit
  • Freight/goods movement
  • Excursion services
  • Bicycle/pedestrian path

Measure D will provide $40,000,000 in funding for the Rail Corridor, for:

  • Preservation of rail corridor infrastructure, including maintaining and repairing the corridor
  • Analysis of future potential uses, including transit and other transportation uses, of the right-of-way through an open, transparent public process

The Unified Corridor Investment Study analyzes a range of transportation uses of the rail corridor including transit (rail or bus) and a bicycle/pedestrian trail. See the Monterey Bay Sanctuary Scenic Trail/Coastal Rail Trail section for more the rail trail.

$5 million from Measure D revenues are specifically designated to construct a safe passage for wildlife to cross under Highway 17 near Laurel Curve. This project is jointly funded by Caltrans and the Land Trust of Santa Cruz County. Read more information on the project.

Caltrans presented information about the project at a Public Information meeting in Scotts Valley on May 2, 2018 and to the RTC board on May 3, 2018. View the Caltrans presentation.
