Summer rain has negatively affected construction on some major road projects across the city. Officials are now hoping a turn in the weather will get road work back on track.

The city's top transportation official says he's keeping his fingers crossed that there will be good news for motorists using the Quesnell Bridge. Byron Nicholson says he knows the traffic delays can be a nuisance for drivers entering Whitemud Drive from 149th St.

"Our goal at the end of this year is to have three lanes going in each direction," he said.

But some aspects of the road work may be delayed. Nicholson says the pedestrian walkway will likely not be ready.

"How much depends on the weather," he said.

And yet despite the gloomy summer weather, officials behind the massive expansion of the Anthony Henday Drive say the project is progressing.

"We do anticipate, barring extreme adverse weather, to have these bridges open this year," said Mark Basher with the City of Edmonton's transportation department.

By the end of October, it's expected that traffic should be able to cross bridges at 184 St. and 170 St., along with St. Albert Trail and 97 St. over top of the Anthony Henday.

Construction on 25 other bridges and road paving will continue as weather permits. Basher says once complete, commuters will be able to drive 21 kilometres, from Yellowhead Trail to Manning freeway without traffic lights.

"Scheduled opening is the first of November 2011. We'll be busy pretty much up to that date," he said.

And Basher assures motorists that crews will meet that date.
