The Town of Newmarket is conducting infrastructure upgrades in the Old Main Street area (see map below for more information). Significant infrastructure improvements are required on Old Main Street to upgrade the existing water, wastewater, stormwater and road infrastructure to support the community.
The proposed work includes:
- Upgrading the existing water, wastewater and road infrastructure
- Installing new stormwater management infrastructure
- New sidewalks to improve accessibility and safety for pedestrians
Project benefits
Once complete, the Old Main Street area will have new critical infrastructure to support the community, and new storm sewers to prevent flooding, which has been an issue in the past.
