Dartmouth Bypass / Forest Hills Extension

The section of Highway 107 between Trunk 7 (at Forest Hills) and Highway 118 has also been known as the Dartmouth Bypass, or Forest Hills Extension. The first section of the bypass (from Trunk 7 to the interchange at Montague Road) opened to traffic in 1985/86.^[6] The remaining section, connecting to Highway 118, opened in 1986/87.^[4]

A short extension to Akerley Boulevard in the Burnside Industrial Park was constructed in the early 1990s.

Twinning of the section between Burnside (which is already twinned) and a point southeast of Exit 14 (Montague Road) began in 2024 and is expected to be completed in 2028/29.^[7]

Burnside/Sackville extension

The section from Akerley Boulevard, along the southwestern side of Anderson Lake, to Exit 4C on Highway 102 opened to traffic on December 20, 2024.^[8] This extension, known locally as the Burnside Expressway, allows commuters from Halifax and Burnside heading to Sackville to bypass the Bedford Bypass and Windmill Road and instead go through Burnside and connect directly into Sackville. The western terminus includes connections to Highway 102, Duke Street and Glendale Avenue. New exits were also constructed at Akerley Boulevard, Burnside Drive, and at a future connection near Anderson Lake.
