The opening of Ides Hill Commerce Way, which connects Tiffany Street on the west with County Street on the east, created a new route to be used for cross-town trips. The resulting new travel patterns were expected to reduce traffic volumes and improve safety in some parts of the City, particularly the southern portion of Tiffany Street and County Square. Vehicle traffic was projected to increase on the South Avenue corridor (Route 123) and the northern segment of Tiffany Street connecting to Commerce Way, since this is the most direct access to the Industrial Business Park from Interstate 95.
For Phase II of the Tiffany Street improvement project, Nitsch Engineering designed roadway operational and safety improvements for 0.7 miles of Tiffany Street and its signalized intersection with South Avenue. We designed full-depth roadway reconstruction, new traffic signal controls, and new sidewalks and handicapped-accessible curb ramps. As part of the roadway reconstruction and widening, Nitsch Engineering replaced the culvert that carries Fourmile Brook under the roadway. The project is in a sensitive area because of the adjacent City drinking water supply, and therefore required careful integration of the stormwater management system. Nitsch Engineering’s approach to meeting the project’s objectives is based on:
- Being sensitive to the environmental resources and Water Resources Protection District associated with Orrs Pond (the City’s drinking water supply);
- Being responsive to residential neighborhood safety concerns for all users of the corridor: vehicles, pedestrians, and bicyclists;
- Providing designs that are context sensitive and can be implemented in a sustainable manner;
- Developing designs consistent with Attleboro Planning Board Rules and Regulations; and
- Designing improvements in compliance with the process and standards of MassDOT Highway Division and the American Association of State Highway and Transportation Officials (AASHTO) guidelines.
The project is receiving state and federal funds through the Transportation Improvement Program (TIP). Construction is estimated to be complete in Summer 2016.
