Route 4 (Massachusetts)

Route 4 (Massachusetts) is a short north–south numbered state highway in Essex County, Massachusetts. The route connects coastal arterial U.S. 1 and I-95/U.S. 1 corridors, passing through urban and suburban neighborhoods of Danvers and Peabody. It serves local commuter traffic, links to regional rail and bus services, and interfaces with commercial centers and municipal facilities.

Route description

Route 4 begins at a signalized intersection with U.S. 1 near the Danversport section of Danvers and proceeds north along a four-lane boulevard that parallels the Danvers River and access routes to Route 62 and local collector streets. Within Danvers the route passes municipal landmarks near Endicott Park, crosses under the Newburyport/Rockport Line of the MBTA Commuter Rail and intersects commercial arterials serving retail near Kingston Collection–adjacent shopping areas. Entering Peabody, the highway transitions to a divided roadway, intersects Route 114 and provides access to industrial zones, the Peabody Institute Library district and commuter parking serving Northshore Mall and the Commuter Rail stations. The route terminates at a partial interchange with I-95/U.S. 1 north of downtown Peabody, where traffic disperses to regional routes toward Salem, Lynn and Boston.

History

The roadway that became Route 4 follows 19th- and early 20th-century local turnpike and town road alignments connecting Salem harbor communities to inland market towns such as Peabody and Danvers. During the expansion of the Massachusetts numbered highway system in the 1920s and 1930s, the corridor was designated to formalize connections between U.S. 1 and the growing New England Interstate Roadway Network. Mid‑20th-century improvements coincided with construction of I-95 and suburbanization driven by postwar development tied to employers in Salem and the Northeast Corridor. Reconstruction projects in the 1970s and 1990s widened sections to accommodate commercial traffic and adjusted intersections near Peabody Square to improve movements to Route 114. More recent pavement rehabilitation and signal modernization efforts were coordinated with agencies including the Massachusetts Department of Transportation and regional planning organizations such as the North Shore MPO.

Major intersections

- Southern terminus: intersection with U.S. 1 in Danvers — access to Route 62 corridors toward Beverly, Salem. - Junction: local connector streets providing access to MBTA Commuter Rail stations on the Newburyport/Rockport Line and park-and-ride facilities used by MBTA bus routes linking to Logan International Airport and North Station. - Intersection with Route 114 in Peabody — movements toward Lynnfield and Marblehead. - Northern terminus: partial interchange with I-95 / U.S. 1 in Peabody — regional access to I-93, Route 128 belt, and I-95 corridors north to Haverhill and New Hampshire.

Traffic and safety

Traffic volumes on Route 4 reflect a mix of commuter, retail and truck movements associated with nearby commercial centers and industrial parks serving companies headquartered in the North Shore region. Peak-hour congestion is concentrated at signalized junctions near Peabody Square and the Route 114 interchange, with periodic queuing reported during holiday shopping periods at the Northshore Mall trade area. Safety analyses by the Massachusetts Department of Transportation and the Essex County planning agencies have identified crash clusters at older skewed intersections and at crossings near MBTA grade-separated facilities; countermeasures have included signal timing optimization, left-turn lanes, and pedestrian refuge islands in coordination with Massachusetts Highway Safety Improvement Program priorities. Emergency response routing uses Route 4 as an arterial connector for Peabody Police Department, Danvers Fire Department and regional ambulance services, and winter maintenance is administered by municipal public works departments in accordance with statewide roadway treatment protocols.

Future plans and improvements

Planned improvements emphasize multimodal access, intersection upgrades, and pavement rehabilitation driven by regional capital investment programs administered by the Massachusetts Department of Transportation, North Shore MPO, and local municipalities. Proposed projects under consideration include reconstruction of select intersections to improve turning radii for trucks serving distribution centers, enhanced signal coordination to reduce corridor travel time to I-95 and U.S. 1, addition of bicycle lanes or shared-use shoulders to support connections to Danvers Rail Trail alignments, and streetscape enhancements in downtown Peabody to support transit-oriented development around commuter rail links. Funding proposals have been advanced through state bond bills and federal surface transportation grants administered via the Federal Highway Administration, with phased implementation tied to environmental review and public comment processes led by Massachusetts Environmental Policy Act review authorities.
