Champlain Bridge superbeam facelift nearly complete

Traffic was slow-going on the Champlain Bridge Sunday as workers put the finishing touches on the span’s brand new superbeam.

The 75-tonne steel reinforcement beam was attached to Canada’s busiest bridge after lengthy delays on Saturday.

Post-tensioning, structure inspection and installation of concrete barriers was completed on Sunday.

Yesterday, the bridge was supposed to be closed from 2 to 7 a.m. ET, but it only reopened around 6 p.m. ET.

The superbeam is meant to help support a cracked girder in a section of the span’s underside.

The crack was discovered in mid-November and since then, traffic on the Champlain Bridge has been reduced.

Drivers commuting to and from the South Shore will have to use just one lane in either direction until Monday during rush hour.

Federal Transport Minister Denis Lebel is expected to speak to reporters this afternoon about the Champlain Bridge.  

CBC Montreal will have more for you on what Lebel said later in the afternoon.
