The Pine Pass, in the Hart Ranges of the Northern Rockies of British Columbia, connects the Peace Country of the province's Northeastern Interior.

In attempts from the east in 1873 and west in 1875, surveyors Charles Horetzky and Alfred Richard Cecil Selwyn, respectively, failed to rediscover the pass.

[7] No doubt motivated by the possibility of securing a "branch" line to Vancouver later (which proved unsuccessful), this decision hindered the Canadian Northern Railway, whose intention to follow this route was publicly known.

[23] During 1930, when the Northern Alberta Railways extended westward toward Dawson Creek, the CPR was again surveying routes across the Canadian Rockies.

Although Monkman Pass was the shortest distance, a more northerly route better served the agricultural lands and mining prospects of the Peace Country.

[24] In 1945, the PGE formally filed plans for the Pine Pass route, because it was 100 miles (160 km) shorter,[25] but lobbying for Finlay Forks continued.

[39] In 1967, the PGE carried the 77-ton turbines for the W. A. C. Bennett Dam, which at the time set a record for the highest load in relation to its width transported on the line.

[41] When a seven-week strike ended in January, 1975, it took several days to remove the snow and ice buildup in the pass before services resumed.

[46] A grain-hauling agreement between BC Rail and CNR established equal shipping rates for Peace area grain to Vancouver and Prince Rupert ports.

[3] In 1930, the district provincial engineer intimated the cheaper Pine Pass route, with an estimated $800,000 cost, would be chosen for a highway.

An alternate Peace Pass/Finlay Forks route proposed a connection through Manson Creek to the highway under construction from Fort St.

[48] The latter, known as the Turgeon Highway continued to receive federal funding as a mining road,[49] but the public support was behind another option, the Monkman Pass.

[53] The prime contractor for the southwest section, Campbell Construction, experienced extreme unforeseen difficulties,[54] and abandoned the uncompleted project.

[61] In the spring of 1955, the section south of the pass to the Parsnip River was approaching impassibility, with three stretches negotiated by Highway Department equipment towing all traffic.

[71] Throughout 1994–96, TNL Paving undertook a $10 million reconstruction of the 11.4-kilometre (7.1 mi) Bijoux Falls to Azouzetta Lake section, applying a porous three-inch diameter gravel foundation.

[88] Several investors owned the Azu Ski Village, which opened in 1965 and eventually grew into four runs with a T-bar and an 4.5-hectare (11-acre) weekend cottage subdivision.

[96] Opened in the early 1950s and for sale in 1963, the Pine Valley Lodge, operating at Mile 171 (an eastern extremity, 39 km [24 mi] west of Chetwynd), comprised cabins, a café and garage.

[109] During 1952, Westcoast Transmission survey crews marked a route through the pass for a natural gas pipeline to the lower mainland.

To facilitate the transmission of higher volumes of gas, the single pipeline was upgraded to narrower pipes laid in dual formation.

[71] With the 2011 heavy rain and flooding, Pembina temporarily shut down its oil pipeline as a proactive measure before rectifying erosion and assessing the line for damage.

[119] During the late 1980s, the Ministry of Health installed repeater stations in the pass to address reception problems experienced by first responders.

[121] The regional district approved the installation of a water and sewer system at an amortized cost of $351,440 that was recovered from users over subsequent years.

Withholding their children from school, an unwillingness to compromise, and lobbying,[125] parents pressured the province to resume the service,[126] which lapsed when no longer required.

[132] In 1959, a solo commercial pilot experiencing engine trouble, died on crashing near Mount Le Moray and the PGE right-of-way.

[137] During the 1997–98 highway reconstruction project, Dale Rolland Alexander assaulted a flagperson on duty in the early hours of the morning,[138] but was not located and remanded in custody until 15 months later.

[143] The hearings during 2001–02, included the victim impact statement, and noted an unsuccessful appeal, his attitude of denial, an unrelated assault on a police officer, and threatening to kill his former mother-in-law.

After he failed to return to his halfway house in Vancouver, as required under the conditions of his long-term supervision order, a Canada-wide arrest warrant was issued in 2013 for the high-risk sex offender.
