Massachusetts exit renumbering was a statewide program to convert sequential exit numbers to mileage-based exit numbers on Interstate and limited-access routes. The initiative involved coordinated planning by the Massachusetts Department of Transportation, compliance with policies from the Federal Highway Administration and guidelines from the American Association of State Highway and Transportation Officials, and operational work on corridors including the Massachusetts Turnpike, Interstate 90 (Massachusetts), Interstate 93, and other numbered routes.
Background
The project arose from national efforts following policy shifts involving the Manual on Uniform Traffic Control Devices and interstate standards, and was informed by precedents in states such as New York (state), New Jersey, Vermont, and Maine. Stakeholders included regional planners from the Boston Metropolitan Planning Organization, authorities from the Metropolitan Area Planning Council, and municipal officials from cities like Boston, Springfield, Massachusetts, Worcester, Massachusetts, Lowell, Massachusetts, and Pittsfield, Massachusetts. Historical context referenced earlier numbering practices established during the era of the State highway engineering expansions and frameworks influenced by the Federal-Aid Highway Act of 1956. Safety analyses cited research from institutions including Massachusetts Institute of Technology, Tufts University, and University of Massachusetts Amherst.
Implementation Timeline
Planning phases referenced meetings at the Massachusetts State House, alignments with federal fiscal cycles, and coordination with construction seasons in the spring and summer months. A pilot phase considered signage inventory methods used in Connecticut, Rhode Island, and New Hampshire. Public outreach included hearings with representatives from the Boston City Council, Worcester City Council, and county commissions in Suffolk County, Massachusetts and Hampden County, Massachusetts. The main rollout began in the mid-2010s, with notable milestones tied to funding approvals from the Massachusetts Legislature and technical directives from the Federal Highway Administration Office of Operations.
Routes and Affected Exits
Primary corridors included Interstate 90 (Massachusetts), Interstate 84 (Connecticut–Massachusetts), Interstate 91, Interstate 93, Interstate 95, and state-numbered limited-access highways such as Route 24 (Massachusetts), Route 3 (Massachusetts), and Route 128. The Massachusetts Turnpike Authority and Massachusetts Bay Transportation Authority interfaces required adjustments near interchanges serving Logan International Airport, South Station (MBTA), North Station (Boston), and park-and-ride hubs. Bridges and tunnels under the purview of the Massachusetts Department of Transportation such as the Sumner Tunnel, Callahan Tunnel, Ted Williams Tunnel, and river crossings like the Zakim Bunker Hill Bridge were considered for signage approaches. Rural exits in counties like Berkshire County, Massachusetts and Barnstable County, Massachusetts were renumbered alongside urban interchanges in Cambridge, Massachusetts and Quincy, Massachusetts.
Signage and Engineering Changes
Signage replacement followed standards from the Manual on Uniform Traffic Control Devices and manufacturing contracts issued through the Massachusetts Operational Services Division. Engineering adaptations involved dynacards, overhead guide signs, ground-mounted plaques, and milepost recalibration similar to installations in Pennsylvania, Ohio, and Michigan. Contractors coordinated with utilities regulated by the Massachusetts Department of Public Utilities and traffic control protocols overseen by the Massachusetts State Police (SPVMassachusetts) for lane closures. Wayfinding updates extended to intermodal nodes like Logan International Airport, Port of Boston, Logan Express, and ferry terminals serving Boston Harbor Islands.
Public Response and Legal Issues
Public comment referenced concerns from commuters, trucking firms including regional chapters of the American Trucking Associations, local chambers of commerce such as the Greater Boston Chamber of Commerce, and municipal leaders including mayors of Boston, Springfield, Massachusetts, and Worcester, Massachusetts. Advocacy groups like the Massachusetts Bicycle Coalition and historical societies for towns like Salem, Massachusetts and Plymouth, Massachusetts weighed in on signage legibility. Lawsuits and procedural challenges invoked administrative review processes in venues including the Massachusetts Appeals Court and filings referencing statutory authority of the Massachusetts Department of Transportation Board. Coordination with the Attorney General of Massachusetts occurred for consumer notification and procurement compliance issues.
Costs and Funding
Budgeting drew on capital appropriations passed by the Massachusetts Legislature and allocations from the Federal Highway Administration Fiscal Year programs. Cost estimates compared sign manufacturing and installation expenses to similar projects in New York (state), New Jersey, and Virginia. Contracts were bid through the Massachusetts Operational Services Division with vendors experienced in highway signage, reflective sheeting technologies developed by firms showcased at the Consumer Electronics Show and standards from the American Association of State Highway and Transportation Officials. Funding discussions included representatives from the Massachusetts Highway Department and fiscal oversight by the Commonwealth of Massachusetts budget office.
Outcomes and Future Plans
Outcomes reported by the Massachusetts Department of Transportation included updated mileposts, new exit plates, and integration into mapping databases used by companies such as Google, Apple Inc., TomTom, and HERE Technologies. Transportation researchers at MIT and University of Massachusetts Amherst evaluated effects on route guidance, emergency response times for agencies like the Boston EMS and Massachusetts State Police, and freight routing efficiency for carriers registered with the Massachusetts Registry of Motor Vehicles. Future plans referenced routine maintenance, continued coordination with corridor improvement projects like the I-93 improvement program and transit-oriented initiatives near South Station (MBTA) and North Station (Boston), and alignment with interstate standards overseen by the Federal Highway Administration and the American Association of State Highway and Transportation Officials.
