Municipal infrastructure projects move through a public process: engineering assessments, board discussions, funding votes, and (where required) state and federal review. This section documents Mendon's path for the Providence Street culvert replacement and what remains open for public input.
Each panel covers one part of the public process.
Engineering determination
The Town engaged Tighe & Bond to assess the failing twin 36-inch corrugated metal pipes and design a replacement. Their assessment found that material fatigue, corrosion, and inadequate hydraulic capacity made repair insufficient — the existing structure cannot be brought to current safety and environmental standards without replacement. The replacement design — a three-sided pre-cast concrete box culvert bridge with a 19-foot span — was the product of that engineering process. The Traffic Plan Memo documents both the structural analysis and the recommended detour configuration.
Funding authorization
Construction cost is approximately $2.1 million; engineering design and oversight is approximately $400,000 depending on the level of oversight selected. Funding sources:
- DER Stream Crossing Grant: $116,000 awarded (supports engineering)
- DOT Grant: $100,000 awarded (supports engineering)
- DOT Construction Grant: $1,000,000 applied (pending award)
- Local municipal capital allocation: balance funded through Town Meeting appropriations, including debt
Annual Town Meeting warrant Articles 14 and 15 provide for the local funding component.
Capital appropriation details and vote records are available through the Agenda Center.
Traffic plan and staff review
The Traffic Plan Memo prepared by Tighe & Bond established the one-way Cemetery Street configuration as the engineering recommendation. Ahead of the April 15 meeting, the Select Board collected resident questions about Cemetery Street traffic and assigned them to Police, Fire, Highway, MURSD, and Tighe & Bond for formal response.
The compiled staff responses are available on the Cemetery Street Q&A page. They address engineering alternatives, emergency vehicle access, school bus routing, road geometry, enforcement, and other resident concerns.
Citizen petition — ruled out of order
A citizen petition with 15 certified signatures was submitted for the Spring 2026 Annual Town Meeting warrant (Article 16). It requested two-way traffic on Cemetery Street and included a funding restriction clause.
Town Counsel has advised that the article is out of order. Town Meeting has the authority to appropriate funds, but the Select Board retains authority over traffic regulations — Town Meeting cannot restrict or interfere with the Select Board's statutory obligations. The petition will not be heard at Annual Town Meeting.
The traffic decision remains with the Select Board, which holds statutory authority over traffic policy under Massachusetts law.
April 15, 2026 decision
Wednesday, April 15, 2026 — 6:30 PM — Upper Town Hall Meeting Room. The Select Board voted unanimously to keep Cemetery Street one-way during construction, adopting the engineering recommendation from Tighe & Bond.
The Board issued two directions to staff alongside the vote:
- Minimize the Providence Street closure duration. Staff and the engineering firm were asked to build the bid package and contractor selection process around minimizing the length of the full closure, without compromising safety or design standards.
- Communicate with residents in three phases.
- Rolling updates as new information becomes available — bid results, contractor selection, permit milestones.
- A general information session for residents before the closure begins, once a firm construction window is in hand.
- Regular project updates during construction itself, so residents know what to expect week-to-week.

Meeting packet: The full meeting packet — including the agenda, staff response document, resident correspondence, meeting minutes for approval, and the draft Annual Town Meeting warrant — is available through the Agenda Center.
Ongoing flexibility: The Select Board reserves the right to revise traffic plans based on new information, safety findings, or operational needs — up until the project breaks ground. Prudent adjustments remain possible if conditions change before construction.
