What is this project about?
This project aims to reduce flooding along Route 1 where it crosses Scarborough Marsh while improving safety and access for all users, including drivers, bicyclists, and pedestrians.
Why is this project needed?
This section of Route 1 frequently floods during high tides and storms. The project is designed to make the roadway more resilient to changing weather conditions and sea level rise.
Where is the project located?
The project extends approximately 1 mile along Route 1, starting about 0.39 miles northeast of Harlow Street and continuing to Southgate Road.
What improvements are being proposed?
Key improvements include:
• Raising the roadway more than 4 feet above the highest astronomical tide
• Replacing existing culverts with a 75-foot bridge over the Dunstan River
• Reconfiguring the roadway to include a multi-use path for walking and biking
What will the new roadway look like?
The proposed project roadway design includes:
- Three travel lanes (one northbound, two southbound)
- A 10-foot multi-use path
- 4-foot shoulders
- 10’ Multi-use path
The proposed design is from the Collaboration between MaineDOT & Town of Scarborough Staff. This design also stays within the existing roadway footprint to protect(minimize) the surrounding marsh.
Why is one northbound lane being removed?
Environmental constraints prevent widening the roadway. To add a multi-use path, one northbound lane will be converted while maintaining overall traffic flow.
Will reducing a lane cause traffic delays?
Traffic modeling suggests minimal impact on delays. However, a pilot project will test this in real-world conditions to confirm performance.
What is the purpose of the multi-use path?
The path will provide a safe, dedicated space for bicyclists and pedestrians, addressing a need identified in local plans and community feedback.
What is the pilot project?
The pilot project is a temporary test of the proposed lane configuration. It will help evaluate how traffic flows and identify any issues before final design decisions are made.
When will the pilot project take place?
The pilot is scheduled for summer 2026, including:
- June 15, 2026: Temporary traffic pattern begins
- August 10, 2026: Roadway restored to current layout
What should I expect during the pilot?
- Temporary lane changes using cones, barriers, and striping
- Message boards and public notices
- Possible changes in traffic patterns
- Traffic monitoring equipment along the corridor
Will the multi-use path be included in the pilot?
No. During the pilot, bicyclists and pedestrians will continue using existing shoulders.
How will the pilot project be evaluated?
MaineDOT will collect data on:
- Travel times and delays
- Traffic flow and congestion
- Safety conditions
- Driver behavior
The results will be compared to earlier traffic modeling.
What happens after the pilot?
The data will be reviewed and used to determine whether the proposed design should move forward. Results will be shared with Town Council and the Public.
Is the project funded?
Funding is currently in place for preliminary engineering and design. Funding for final design and construction has not yet been secured.
How can I stay informed?
Updates will be shared through:
- Town of Scarborough website
- Town Council Workshop on May 6th, 2026 plans will be presented
- Media and social media outreach
- Upcoming Town Council Meeting (date not yet determined) to share Pilot data results.
How can I provide input?
Community feedback is encouraged. Share comments with the Town of Scarborough and can also reach out to Ernie Martin, MaineDOT Project Manager, with any comments or questions.
