A HIGHWAY FOR THE BLACKSTONE VALLEY: During the late 1940's, the Massachusetts Department of Public Works (MassDPW) planned an extension of Route 146 from Rhode Island north toward Worcester. The proposed route was to be an extension of RI 146 (Louisquisset Pike), which was Rhode Island's first dualized highway.
The MassDPW built MA 146 as a four-lane divided roadway (two lanes in each direction) from US 20 in Millbury south to Boston Road in Sutton, with a narrow median separating the opposing traffic flows. From Sutton south to the Massachusetts-Rhode Island border, MA 146 was built as a three-lane undivided roadway, providing one lane in each direction and a shared lane in the center (striped for use in both directions along various sections of the roadway). Like RI 146 to the south, these sections of MA 146 provided partial control of access: although there were some grade separations, at-grade intersections and curb cuts were not uncommon. These sections were built between 1949 and 1952.
The completed sections of the new MA 146 provided traffic relief along the Blackstone Valley, particularly along MA 122. However, the improvements stopped about three miles shy of downtown Worcester. North of US 20, MA 146 continued as a two-lane local street.
BRINGING ROUTE 146 UP TO STANDARDS: By the mid-1960's, it had become clear that the Worcester-Providence Turnpike was unable to meet traffic demands. Anticipating even greater traffic demands around the Worcester area during the next 20 years, the state developed plans for a modern four-lane freeway along the MA 146 corridor from the Massachusetts-Rhode Island border north to I-290. The 21-mile-long freeway was estimated to cost between $40 million and $50 million in 1965 dollars.
It was not until 1981 that the MassDPW began work on rebuilding MA 146. During the next three years, the state rebuilt the 13.1-mile-long section from just south of Boston Road in Sutton to the Massachusetts-Rhode Island border, replacing the three-lane undivided section with a four-lane freeway. In contrast to the older four-lane section to the north, a wide grassy median separated opposing traffic flows. The state also established a "no-cut" line along this section of MA 146, eliminating all at-grade intersections and curb cuts. It even moved a cemetery in the path of the highway that belonged to a former almshouse in Uxbridge at the cost of $107,500.
REBUILDING ROUTE 146 THROUGH WORCESTER AND MILLBURY: By the mid-1990's, there remained no connection between MA 146 and the Massachusetts Turnpike (I-90). In addition, MA 146 still had not been widened: it narrowed from a four-lane divided highway in Millbury to a two-lane street approaching Worcester. In 1994, the Massachusetts State Legislature approved a $6 billion statewide highway bill that included a $290 million upgrade of MA 146 to a freeway through Millbury and Worcester, along with a long-awaited connection to the Massachusetts Turnpike.
The four-lane freeway upgrade of MA 146 was to follow the tenets of "context-sensitive" design, meaning that it was to reflect the historic nature of the BlackstoneValley. A limited right-of-way was to be used for the freeway footprint, and opposing traffic flows were to be separated by a concrete ("Jersey") barrier adorned with decorative lightposts. A bike path also was incorporated into the design of the freeway. It required the location of 105 homes and 56 businesses, as well as the cleanup of several former industrial sites.
The first part of the project was the connection between MA 146 and the Massachusetts Turnpike. Work on the $89 million interchange began in early 1996. It included upgrading the existing four-lane MA 146 to a freeway in the immediate vicinity of the interchange, building access roads to the Massachusetts Turnpike and US 20 (Southwest Cutoff), constructing a new bridge to carry US 20 over MA 146 and the Blackstone River, and creating a new park-and-ride facility. The connection between the turnpike and MA 146 opened to traffic in late 1998, and the "upper J connector" (named for the shape of the connector as depicted on a map) to US 20 followed in early 2001. The connection between the turnpike, MA 146, and US 20 is not a direct one: motorists must pass a three-way traffic light on the MA 146-US 20 ("upper J") connector road before reaching their destination.
During the early-to-mid 2000's, the MHD followed up with the completion of the following projects on MA 146:
In March 2002, another milestone for MA 146 passed with the one-mile-long extension of the freeway section south to MA 122A (Main Street), where a new $33 million interchange was built. The interchange provides access to The Shoppes at Blackstone Valley, a regional mall that opened one year later.
In September 2003, the 1.5-mile-long "Kane Square" segment of MA 146 freeway opened to traffic. The $57 million extension just north of the I-90 / US 20 interchange provided a new interchange for Millbury Street.
In November 2005, the MHD extended the MA 146 Expressway through Hurley Square. The $40 million project included the construction of a new bridge to connect McKeon Road and Providence Street over the new MA 146, along with a new two-lane frontage road to the east of the new freeway. Construction crews also built a 1,700-foot-long flood relief conduit for the Blackstone Canal to alleviate flooding in the nearby Green Island neighborhood.
According to the Massachusetts Highway Department (MHD), the completed freeway sections of MA 146 handle approximately 25,000 vehicles per day (AADT). This figure is expected to increase significantly upon completion of the remaining Worcester and Millbury-to-Sutton freeway sections.

MAKING THE FINAL CONNECTION TO WORCESTER: At Hurley Square, a new bridge was built to connect McKeon Road and Providence Street over the new MA 146, while a new two-lane frontage road was built to the east of the new freeway. Construction crews also built a 1,700-foot-long flood relief conduit for the Blackstone Canal to alleviate flooding in the nearby Green Island neighborhood. The MA 146 extension through Hurley Square is scheduled to open in November 2005.
The final phase of the 12-year project involves building a 1.5-mile-long extension of the MA 146 freeway, as well as rebuilding the interchange between MA 146 and I-290. New ramps connecting MA 146 northbound to I-290 eastbound, and from I-290 westbound to MA 146 southbound, would be built at the interchange, which would replace the current rotary at Brosnihan Square. MA 146 will continue past the interchange as two-lane Quinsigamond Avenue. The parallel Providence and Worcester Railroad tracks also are being realigned as part of the freeway extension. Scheduled for completion in December 2007, the $60 million final leg of the MA 146 extension and Brosnihan Square interchange projects was delayed because of delays by Worcester officials to come up with funds to purchase four parcels for the interchange and related street widenings.
CLOSING THE MISSING FREEWAY LINK FROM MILLBURY TO SUTTON: In October 2001, the MHD and the Central Massachusetts Regional Planning Commission initiated studies on the existing four-lane undivided section of MA 146 from the MA 122A (Main Street) interchange in Millbury south to the Central Turnpike interchange in Sutton. Built during the 1930's and 1940's, this 4.1-mile-long section of MA 146, which handles approximately 25,000 vehicles per day (AADT), suffers from substandard design. Traffic lights and curb cuts only make matters worse, though the closure of median crossovers during the early 2000's have provided a stopgap measure of safety.
The two agencies recommended the following $16 million intermediate-term program to upgrade MA 146. Construction of these projects would not be expected to begin until at least 2010:
The existing grade-separated interchange at Elm Street in Millbury would be upgraded with a new MA 146 mainline bridge over Elm Street, rebuilt entrance and exit ramps, and extended acceleration-deceleration lanes.
The existing signaled intersection at Boston Road in Sutton would be upgraded to a grade-separated interchange. In addition to a new bridge for Boston Road over MA 146, there would be new frontage roads built from Boston Road south to Central Turnpike. The existing Pleasant Valley Road would be rebuilt to connect traffic entering and exiting MA 146 northbound to Boston Road. The southbound frontage road would connect traffic entering and exiting MA 146 southbound to Boston Road.
Long-range plans call for the construction of continuous frontage roads to serve businesses along MA 146. They also call for the construction of an overpass at Deborah Drive in Sutton. No cost estimate has been provided for these long-range plans.
This 2005 photo shows the overpass being built to connect McKeon Road and Providence Street over the new Worcester-Providence Turnpike (MA 146). The "Hurley Square" section of MA 146 shown here was completed in November 2005, with completion of the "Brosnihan Square" section and the MA 146 / I-290 interchange slated for December 2007.

EXTEND I-190 SOUTH TO PROVIDENCE: The I-190 designation should be extended to MA 146 and RI 146 from Worcester south to Providence (via I-290) upon completion of all sections to freeway-grade status. Exits should be numbered upon the completion of the MA 146 (I-190) conversion.
