Alberta looks to protect bridges from big trucks with fines, 'naughty list' for truckers

Alberta's transportation minister could hear the horns blaring from inside his office.

It wasn't from a rally or protest on the Edmonton legislature grounds but, as Devin Dreeshen went outside to discover, the sound of confused and angry drivers.

"It was a truck that had hit [the bridge] and was stopped and backing up traffic all the way up 109 Street," he recalled of the summer gridlock.

Five times this year, large trucks heading onto the double-decker High Level Bridge, a stone's throw west of the legislature, have hit the structure. Ten other times, trucks stopped before it was too late.

Dreeshen is hoping the government can fix the problem right outside its door, with new policies — and potential fine increases for truckers.

The 112-year-old steel truss bridge is a striking feature in the core of Alberta's capital. It reaches high above the North Saskatchewan River and stretches more than 750 metres across.

It originally supported horses and buggies, trains, early automobiles and streetcars. The Canadian Pacific Railway, which built the bridge, stopped running freight on the upper deck in 1989.

The lower level has a clearance of 10.6 metres, meaning a bus fits with just centimetres to spare. Most semis and other big rigs are a no-go.

Bright yellow signs along the preceding meridian warn trucks to turn off before it's too late, but many try to squeeze on anyway.

Police say the bridge has been hit 21 times in the past six years, with 63 close calls of trucks stopping in time but creating traffic jams by having to back out.

It's not a new phenomenon. Photos of trucks mangled by the bridge, dating back at least 50 years, can be found in the city's archives.

Construction of the bridge was considered a key reason why the cities of Edmonton, on the north side of the river, and Strathcona, on the south, amalgamated in 1912.

That achievement was partly why the bridge was designated a local historic resource in 1995, which commits Edmonton to maintain it but not make drastic alterations.

However, some changes have been made.
