The Johnson Street bridge is getting closer to its March completion date as the bridge span is installed this month, leaving just minor tasks to finish the project for good.
The span B次元官网网址 the bridge deck where vehicles, pedestrians and cyclists will cross B次元官网网址 is tentatively scheduled to be lifted Saturday Jan. 27, potentially closing the existing bridge to traffic for the day. The marine channel will be closed for nine days while workers bolt the span to the rings and perform test bridge lifts. The Dynamic Beast, a giant crane barge able to lift over 800 metric tonnes, will arrive a day earlier.
B次元官网网址淚f it doesnB次元官网网址檛 lift at the end of the nine-day period, weB次元官网网址檙e in trouble,B次元官网网址 said engineer and project manager for the bridge Jonathan Huggett, adding that this work will ensure the bridge deck lift mechanism is fully operational.

Construction crews will work overnight if needed to get the project done, he said, but installation could still be delayed pending availability of the crane and unfavourable weather conditions.

In August, Huggett indicated the bridge would B次元官网网址渓ook almost completeB次元官网网址 by Christmas for the $105-million bridge replacement, however the span installation was pushed back to this month. Workers have been using that time to perform work on the span prior to the lift, Huggett said, rather than after it had been attached. Installing the span will be a major step to completing the project, but after those nine days, there is still work to be done.

After the span is installed, workers will place concrete beams to close the gap between the two sides of the bridge, touch up the paint, and perform tests to ensure all parts are operating properly.
Huggett expects crowds to gather and watch as the giant steel structure is lifted into place, as was the case when the two 290-tonne steel rings were installed in early December, and when the steel parts originally arrived from China in early fall.
