TheBurlington Bay James N. Allan Skyway, originally called theBurlington Bay Skyway and simply known as theBurlington Skyway orThe Skyway, is a pair of high-level freeway bridges (built in 1958 and 1985) spanning theBurlington Bay Canal. The Skyway, as it is locally known, is located inHamilton andBurlington,Ontario, Canada, and is part of theQueen Elizabeth Way (QEW) highway linkingFort Erie withToronto. The 1958 steel bridge is a suspended deck through-arch truss bridge. The approach to the main span has elements of a through-truss bridge, but the arch shape takes the truss higher than the roadway deck, so hangers are used to suspend the deck from the arch truss. The truss bridge is 2,560 m (8,400 ft) long overall. The main span of 151 m (495 ft) is flanked by two back spans each 83.7 m (275 ft) long; there are 72 total approach spans, and the bridge has 36.7 m (120 ft) of vertical clearance below the bottom of the deck.[2] The girder bridge, completed in 1985, is 335 m (1,099 ft) shorter. The roadway deck for each bridge is 30 m (97 ft) wide.[4]
The first bridge (steel structure) officially opened on October 30, 1958,[4] crossing the narrow bar separatingHamilton Harbour and thePort of Hamilton fromLake Ontario. This allows forGreat Lakes ship traffic to flow underneath while four lanes ofGolden Horseshoe road traffic may flow on top of it, neither disturbing the other. The bridge was designed by John Turner Bell.[5] Construction of the entire Skyway required 20,000 short tons (18,000 t) of steel and 90,000 cubic yards (69,000 m3) of concrete.[6]
The bridge hadtolls when constructed, but these were removed December 28, 1973[4] after they were found to heavily impede traffic flow. The toll plaza was located near Tower's Drive. Truck drivers in particular had refused to take the tolled bridge since not only were they charged the full toll but also it took them extra fuel to ascend the Skyway.[7] With the lifting of tolls on the bridge, trucks were then banned from usingBeach Boulevard.
When traffic volume became more than the bridge could accommodate in the early 1980s, the bridge was twinned. The 1985 bridge was a conventional precast concrete box girder. When the new skyway (concrete structure) was opened on October 11, 1985,[4] traffic was temporarily rerouted to it so that the old bridge could be extensively rehabilitated and this work was completed August 22, 1988.[4][7] Afterwards, there were eight lanes of traffic crossing the harbour.
The twinning project also saw a major upgrade of the freeway approaches to the bridge. The entire project resulted in the QEW being widened to eight lanes from Burlington Street to Highway 403, with modernParclo interchanges at Burlington Street, Northshore Boulevard (former Highway 2), and Fairview Street/Plains Road. This section has a variable lighting system to overcome the frequent fog found in the area. It is also the site of Ontario's first freeway traffic management system which incorporates traffic cameras and changeable message signs.
The original name of the first bridge was theBurlington Bay Skyway. After it was twinned, the proposed names ofJames N. Allan Skyway (in honour of theOntario Minister of HighwaysJames Noble Allan, who had championed the 1958 bridge) andJames N. Allan Burlington Bay Skyway were rejected. The official name since 1988 has beenBurlington Bay James N. Allan Skyway.[4][7]
In fall 2008, most of the older Aluminum Tapered Leg (ATL) overhead sign gantries (commonly referred by the MTO as a "Type 1" structure) which had been installed back in the late 1980s were replaced with the newer triangular truss gantries.[8][9][10] This included the overhead gantry signage for exit 97 on the northbound span of the skyway.
On July 31, 2014, a man driving adump truck in its raised position crashed onto the top of the bridge frame on the Toronto-bound lanes.[11] The bridge was closed for the weekend to make temporary repairs;[12] permanent repairs to the bridge structure took seven months and cost $1.224 million.[13] The driver was charged with impaired driving and tried in 2016, resulting in a conviction for dangerous driving in March 2016[14] and a one-year jail sentence.[15] His conviction and sentence were upheld by the Ontario Court of Appeal.[16]
