FROM WORCESTER TO LEOMINSTER: As early as 1958, the Massachusetts Department of Public Works (MassDPW) began preliminary planning and engineering studies on a proposed controlled-access bypass of MA 12 from I-290 (then designated MA 122A) in downtown Worcester north to MA 2 in downtown Leominster. The MA 12 Expressway, as it was originally designated, was to be part of a much larger north-south expressway extending south to Connecticut.

In 1965, the MassDPW incorporated the MA 12 Expressway as part of an expressway system serving central Massachusetts. Included in the "Central Corridor Traffic Study" were never-built loops around the western edge of Worcester, and around the eastern edge of Leominster. Two years later, Governor John Volpe approved the north-south freeway - now designated MA 52 - as an extended north-south route connecting Webster (on the Massachusetts-Connecticut border) with Leominster. The route was to connect to the south with the CT 52 Expressway (now designated I-395).

During the next three years, the MassDPW held public hearings on possible locations for the Worcester-Leominster route. The original routing was to be roughly along the existing MA 12, but was changed amid concerns from residents in West Boylston and Leominster:

  • In West Boylston, residents feared that construction of the expressway would divide their town, and would impact nearby Wachusett Reservoir. The alignment of the expressway was shifted to the west.

  • In Leominster, the expressway was originally proposed to run through downtown Leominster to MA 2. Instead, the alignment of the mainline expressway was shifted east to the alignment of the once-proposed Leominster Loop.

The Federal Highway Administration (FHWA) gave preliminary approval to the MA 52 Expressway in 1970. However, because of potential impacts to Indian Lake in Worcester and other environmentally sensitive areas, the FHWA ordered the MassDPW to conduct an environmental impact statement for the proposed expressway.

In 1973, state and Federal agencies approved the final alignment and environmental impact statements. That year, the FHWA approved a new Interstate designation - Interstate 190 - for the MA 52 Expressway north of I-290 (Worcester Expressway). Some of the newly approved Federal funding came from unbuilt highway projects in the Boston area.

Work on I-190 began in 1975. MassDPW selected a modified alignment that minimized community disruption, but even the new route required the relocation of 42 families and six businesses.

POLLUTION CONCERNS HALT WORK, BRING CHANGES: In 1980, the U.S. Environmental Protection Agency (EPA) ordered the MassDPW to stop all work on I-190. The EPA cited concerns that heavy rains would send excessive amounts of dirt and other contaminants into nearby Wachusett Reservoir. State officials complied with the EPA order, but went to court to dispute the EPA findings and resume construction. In 1981, the U.S Court of Appeals in Boston ordered that work resume on I-190, ruling that the environmental impact statement filed by the FHWA was adequate.

The lessons of the delay were not lost on highway planners. When construction resumed, the MassDPW implemented a number of mitigation measures, retaining forested slopes to minimize erosion, constructing grade separations for migratory wildlife, and implementing natural and artificial noise abatement measures. In the area of Wachusett Reservoir, extra-wide left and right shoulders on the highway were designed to keep road salt and other contaminants away from the reservoir. After eight years of construction and delay, the $77 million expressway opened to traffic in 1983.

TRAFFIC COUNTS: According to the Massachusetts Highway Department (MHD), I-190 carries approximately 70,000 vehicles per day along the six-lane section through the city of Worcester, dropping sharply to approximately 25,000 vehicles per day (AADT) along the four-lane section through West Boylston, Sterling and Leominster.

THE UNBUILT HOLDEN CONNECTOR: A USGS topographical map shows a trumpet interchange "under construction" on I-190 just north of the Malden Street overpass in Holden. It is unclear if this connection - the proposed EXIT 4A - was in the original plans for I-190, but the Holden Connector proposal was revived in the early 2000's by officials in Holden seeking to relieve downtown congestion while providing access between MA 122A (Main Street) and I-190. An alternative proposal for EXIT 4A had ramps connecting to an upgraded Malden Street; this proposal had the support of Holden officials, but not from those in the neighboring town of West Boylston to the east. The Holden Connector was not on the most recent (2007-2010) transportation improvement plan published by the Central Massachusetts Metropolitan Planning Organization (CMMPO).

NORTH TO NEW HAMPSHIRE? The 1965 "Central Corridor Traffic Study" proposed an extension of the MA 12 Expressway along the MA 13 corridor through Leominster, Lunenburg and Townsend to the Massachusetts-New Hampshire border. Extending 15 miles north of MA 2, the MA 13 Expressway was estimated to cost $14 million, and was expected to carry 15,000 vehicles per day (AADT) some 20 years hence.

Beginning in 1970, officials from Massachusetts and New Hampshire submitted plans to the FHWA for a 63.6-mile-long Interstate highway connecting I-290 in Worcester with I-293 in Manchester. Two years later, Connecticut officials joined those from Massachusetts and New Hampshire to create a continuous Interstate highway corridor from New London, Connecticut north to Manchester, New Hampshire.

When the FHWA and the MassDPW released their final environmental impact statement for I-190 in 1973, plans for its eventual extension north to I-93 in Manchester were said to be in a "conceptual stage," but no route had been approved. Plans for the northern extension never advanced beyond this stage. Although the FHWA ultimately shelved the 44.5 miles north of Fitchburg, much of the Connecticut-Massachusetts corridor eventually received an Interstate designation: I-190 in 1973, and I-395 in 1983.
