Massachusetts Route 146
Route 146 is a high-speed road, mostly freeway, linking Rhode Island Route 146 (the North Smithfield Expressway towards Providence, Rhode Island) to I-290 in Worcester, Massachusetts. South of the interchange with Route 122A, Route 146 is known as the Worcester-Providence Turnpike. Unlike some roads designated as turnpikes, the road has never had tolls, and was built on a brand new alignment in the 1930s. Similar never-tolled turnpikes are the Berlin Turnpike in Connecticut and the Boston-Providence Turnpike in Massachusetts.
==History==
During the late 1940s, the Massachusetts Department of Public Works (MassDPW) planned an extension of Route 146 from Rhode Island north toward Worcester. MA 146 was built between 1949 and 1952 as a four-lane divided roadway from US 20 in Millbury to Boston Road in Sutton and from Sutton south to the Massachusetts-Rhode Island border, Route 146 was built as a three-lane undivided roadway, providing one lane in each direction and a shared lane in the center.
In 1981 the MassDPW began work on rebuilding Route 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 and eliminating all at-grade intersections and curb cuts.
The project upgrading the section linking Exit 10A on the Massachusetts Turnpike north into downtown Worcester at Brosnihan Square to Interstate Highway standards was completed in November 2007 according to the State Highway Administration. The final construction phase will upgrade the remaining Massachusetts section in Sutton and Millbury to freeway status and is scheduled for completion sometime after 2010.〔(【引用サイトリンク】publisher=Boston Roads.com )〕
