Route 1 (New Brunswick)

Route 1 (New Brunswick) is a major provincial arterial highway in Canada connecting the Canada–United States border at Saint‑Stephen with the Trans-Canada Highway near Sackville via Saint John and Moncton. The corridor links the St. Croix River crossing to interprovincial routes serving Nova Scotia and international corridors toward Maine and the United States. Managed by New Brunswick Department of Transportation and Infrastructure it serves as a key part of regional freight, passenger, and tourism networks such as the Marine Atlantic ferry connections and the Fundy Isles tourism routes.

Route description

Route 1 begins at the international boundary at the St. Croix Crossing near Milltown and proceeds northeast through the Charlotte County community of Saint‑Stephen toward St. George, paralleling the St. Croix River and intersecting provincial routes like Route 170 and Route 3 before reaching the industrial and port city of Saint John. Within Saint John, the highway interfaces with urban arteries serving the Port of Saint John, the Irving Oil refinery complex near Reversing Falls, and the Saint John Harbour Bridge approaches, then continues east along the Fundy Shore toward Rothesay and Quispamsis, crossing waterways linked to Bay of Fundy tides and passing near heritage sites such as Fort Howe. East of Saint John Route 1 becomes a controlled‑access freeway near Welsford and passes through the Kennebecasis River valley, connecting to Moncton via expressway segments that skirt communities including Salisbury and Hillsborough, before terminating at an interchange with the Trans-Canada Highway (Route 2) close to Sackville and the Tantramar Marshes.

History

The corridor traces nineteenth‑ and twentieth‑century transportation links that connected the Port of Saint John with inland markets, following old wagon roads, stagecoach routes, and sections of the historic Intercolonial Railway of Canada. Post‑World War II economic expansion and the National Policy era prompted upgrades linking industrial centres such as Saint John and Moncton, while federal programs influenced design standards via agencies like Transport Canada. Major twinning and four‑lane conversion projects accelerated in the late twentieth and early twenty‑first centuries, driven by investments similar to those for the Trans-Canada Highway and influenced by trade agreements such as the Canada–United States Free Trade Agreement and the North American Free Trade Agreement. Significant modern works include bypasses around urban centres, interchanges constructed under public‑private partnership models reflective of financing approaches used in projects like the MacKay Highway upgrades, and the St. Croix Crossing replacement of the older Milltown International Bridge which involved cross‑border coordination with the Federal Highway Administration and provincial agencies.

Major intersections

The highway's principal junctions include the international crossing at Saint‑Stephen connecting to U.S. Route 1 corridors, major interchanges in Saint John serving the Port of Saint John, a critical interchange with Route 7 toward Fredericton and Prince William, connector ramps to Route 2 (the Trans-Canada Highway) near Sackville, and multiple interchanges providing access to Quispamsis, Rothesay, Salisbury, and Hillsborough. Additional junctions tie into secondary provincial routes such as Route 102, Route 124, and Route 112, facilitating links to regional centres including St. George, Grand Bay–Westfield, and the Tantramar Region.

Traffic and usage

Route 1 supports mixed traffic comprising long‑haul freight carriers linked to the Port of Saint John, intercity buses such as operators formerly represented by carriers connected to Via Rail corridors, commuter traffic for suburbs of Moncton and Saint John, and seasonal tourist movements toward attractions like the Fundy National Park access roads and the Hopewell Rocks Provincial Park. Freight volumes reflect container flows from Atlantic ports and transshipment via corridors used by companies such as Irving Group of Companies and logistics firms serving the Maritime Provinces. Traffic counts vary seasonally with peaks in summer months tied to tourism and in winter with commercial trucking influenced by energy sector deliveries to facilities including refineries and power stations.

Future developments and upgrades

Planned and proposed projects on the corridor include additional twinning and four‑lane conversions to improve safety and capacity consistent with standards used on Trans-Canada Highway upgrades, interchange redesigns near urban growth nodes like Moncton and Saint John, and multimodal integration projects linking highway infrastructure with port and rail terminals such as those serving the Port of Saint John and regional container yards. Proposals also consider climate resilience measures informed by studies from agencies akin to Natural Resources Canada and provincial climate initiatives, plus potential funding and procurement strategies similar to past public‑private partnerships used elsewhere in New Brunswick infrastructure programs. Environmental assessments and stakeholder consultations involve regional municipalities, Indigenous groups such as those represented by Mi'kmaq communities in the Maritimes, and federal environmental review processes.
