It's the Big Lift's last big weekend, but more closures still on deck

It's been a bumpy ride but work toreplace the half-century oldspan of Halifax's Macdonald Bridge is nearly complete.

This weekend marks the final routine Saturday-Sunday closure and will allow the final two deck segments to be replaced. The Big Lift involves replacing 46 deck segments.

As has beendone for nearly two years, the bridge will be closed until Monday morning at 5:30.

Though regular weekend closures are coming to an end, spokesperson Alison MacDonald says about five more weekends areneeded for finishing work, such as paving. Those weekends will be between April and June.

The bridge will continue to close weekdaysfrom 7 p.m. to 5:30 a.m., Sunday through Thursday.

Forging on despite bad weather

Despite rainfall warnings issued by Environment Canada, this weekend's deck replacementswill goahead.

It's an all-or-nothing weekend because theplan requires the 46thdeck segment to be installed before the 45th. If work didn't finish this weekend, there'd be a gap in the span come Monday morning, said MacDonald.

If the wind or rain becomes hazardous for crews, she saidtheir schedule is flexible enough to allow for bad weather to pass.

Strong winds and unfavourable work conditionshavehindered progress, leading to frustrating delays for weekday commuters and schedule postponements.

The original project timeline had projected redecking done by last fall.

Next phase

With the Big Lift on the home stretch, MacDonald saidteams are looking tothe next phase of the project.

Once the final decks are installed, their attention will turn to finishing the walkway and bike lanes on either side of the span. Crews will finish welds and install barriers to have themready in the next four to six weeks.

Sidewalks and bike lanes were originally supposed to reopenby December 2016. The city isreviewing plans to improve the bridge's active transportation lanes.

The Big Lift began in March 2015 and is intended to expand the life of the bridge for decades to come.
