Nova Scotia Trunk 4

Trunk 4 is part of the Canadian province of Nova Scotia's system of Trunk Highways. The route runs from Highway 104 exit 7 near Thomson Station to Glace Bay.[2] Until the construction of the Trans-Canada Highway, Trunk 4 was a major traffic link in northern Nova Scotia and Cape Breton, and is still used on Cape Breton as an alternative to Highway 105. The highway was originally called the King's Highway, however, this name is no longer applied to the entire road. The only remaining historic section of the highway that maintains the name "King" is King's Road in Sydney.

Route description (west to east)
Trunk 4 outside Alma.
Thomson Station to Glenholme

The section between the western terminus at Exit 7, Highway 104 in Thomson Station to Mahoneys Corner was originally built as Highway 104 in the 1960s. It was bypassed by the Cobequid Pass in 1997 and redesignated Trunk 4 at that time. The section between Mahoneys Corner and Glenholme was originally part of Trunk 4 until the 1960s when it was designated Highway 104. This section was also redesignated Trunk 4 in 1997 after the opening of the Cobequid Pass.

Glenholme to Onslow

The section between Glenholme and Onslow is co-designated with Trunk 2. Trunk 4 is discontinuous between Exit 14A, Highway 102 in the west and Pictou Road in Bible Hill in the east.

Bible Hill to Barney's River Station

Trunk 4 reappears in Bible Hill, following Pictou Road and the original Trunk 4 alignment east. In Kemptown, Trunk 4 follows an old alignment of Highway 104 for several kilometres. Trunk 4 continues east of Kemptown on its original alignment through Mount Thom to Salt Springs. From Salt Springs to Westville, the present alignment of Trunk 4 was used as Highway 104 from the 1960s until being bypassed in the 1990s. Now redesignated Trunk 4, the highway designation continues into Westville on Truro Road and then Westville Road. In New Glasgow it follows the original Trunk 4 route on Westville Road, Stellarton Road, George Street, Archimedes Street, Marsh Street and Merigomish Road before heading east toward Sutherlands River. At Sutherlands River, Trunk 4 follows a new alignment between School Rd and Highway 245. It then continues east to Barney's River Station.

Marshy Hope to South River Station

Trunk 4 is discontinuous between Barney's River Station and Marshy Hope as Highway 104 uses the old Trunk 4 alignment for this section. From Marshy Hope, Trunk 4 proceeds east to Antigonish. In Antigonish, it follows Post Road, James Street, Main Street, and St Andrews Street. East of Antigonish it proceeds to South River Station.

Heatherton to Auld's Cove

Trunk 4 is discontinuous between South River Station and Heatherton as Highway 104 mostly uses the old Trunk 4 alignment. From Heatherton, Trunk 4 proceeds east to Auld's Cove.

Port Hastings to Glace Bay

Trunk 4 is discontinuous between Auld's Cove and Port Hastings as Highway 104 uses the old Trunk 4 alignment. From Port Hastings, Trunk 4 proceeds east through Port Hawkesbury and St. Peter's before turning northeast along the southeastern shore of Bras d'Or Lake through Big Pond and Ben Eoin. It continues east to Sydney River to Sydney. In Sydney it follows Kings Road, Esplanade Road, Welton Street. East of Sydney it continues along Grand Lake Road to Reserve Mines and Glace Bay. In Glace Bay it follows Reserve Street and Union Street and ends at the intersection of Union and Commercial Streets.

Blue Route

Because a large portion of the highway has been paralleled by the faster Highway 104, traffic volumes are comparatively light. As a result, parts of Trunk 4 are currently under review to become part of Nova Scotia's Blue Route, a designated cycling corridor.[3]

History

Trunk 4 originally started at the New Brunswick border in Fort Lawrence. In the early years of the Trans-Canada Highway system, Trunk 4 was the designated Trans-Canada Highway route across mainland Nova Scotia. When controlled-access sections of Highway 104 were first built in the 1960s, the number replaced Trunk 4 entirely west of New Glasgow. As four-lane sections of Highway 104 were built in the late 1990s, the number 4 was again used to mark the former Mount Thom and Wentworth Valley sections of 104.
