Route 100 is 49 kilometres long, and runs from Saint John to Hampton, New Brunswick.
Saint John is the coastal port city of the Bay of Fundy in the Canadian province of New Brunswick. The port is Canada’s third largest port by tonnage with a cargo base that includes dry and liquid bulk, break bulk, containers, and cruise. In 2016, after more than 40 years of population decline, the city became the second most populous city in the province for the first time, with a population of 67,575 over an area of 315.82 square kilometres (121.94 sq mi). Greater Saint John covers a land area of 3,362.95 square kilometres (1,298.44 sq mi) across the Caledonia Highlands, with a population of 126,202. After the partitioning of the colony of Nova Scotia in 1784, the new colony of New Brunswick was thought to be named 'New Ireland' with the capital to be in Saint John before being vetoed by Britain's King George III. Saint John is the oldest incorporated city in Canada. During the reign of George III, the municipality was created by royal charter in 1785.
Hampton is a town in Kings County, New Brunswick, Canada.
Route 100 follows the through route across Saint John and the Kennebecasis Valley that was used prior to the construction of the Saint John Throughway and MacKay Highway. The road begins on Saint John's west side using Ocean West Way and Fairville Boulevard, and crosses the Reversing Falls Bridge to Chesley Drive on the north end. It then crosses a viaduct to the city centre, where it takes City Road to the east side, and leaves Saint John on Rothesay Avenue. Route 100 continues as the Hampton Highway through the Kennebecasis River Valley towns of Rothesay and Quispamsis, and uses a former alignment of Route 1 to reach Hampton.
The Reversing Falls Bridge is a two-lane highway bridge crossing the Saint John River at Saint John, New Brunswick, Canada. It carries New Brunswick Route 100 across the river and there is no toll for its use.
A viaduct is a bridge composed of several small spans for crossing a valley, dry or wetland, or forming an overpass or flyover.
The Kennebecasis River is a tributary of the Saint John River in southern New Brunswick, Canada. The name Kennebecasis is thought to be derived from the Mi'kmaq "Kenepekachiachk", meaning "little long bay place." It runs for approximately 95 kilometres, draining an area in the Caledonia Highlands, an extension of the Appalachian Mountains, inland from the Bay of Fundy.
