At the Blue Water, the original 1937 span - one of two spans that make up the bridge, the other being built in 1997 - is being resurfaced and receiving waterproof undercoating.
This span normally serves westbound traffic.
But during construction the other - newer - eastbound span is carrying both westbound and eastbound traffic.
During construction westbound traffic headed to the US, after clearing Canadian toll booths, is being directed to the eastbound span and travelling in the right lane.
At bridge midpoint westbound traffic is split into two lanes - commercial in the centre and passenger to the right.
Meanwhile, eastbound traffic to Canada, after clearing Michigan toll booths, is being directed to the right lane of the eastbound span.
At bridge midpoint eastbound traffic is split into two lanes - passenger traffic to the centre lane and commercial traffic to the right.
Limited lane availability will prevent the use of a dedicated lane for NEXUS and F.A.S.T. motorists, as well as buses.
Meanwhile redevelopment of the Canadian Customs plaza at Sault Ste. Marie will begin a new phase in May with demolition of the old Duty Free Store and construction of new Customs’ facilities.
A new Duty Free Shop, maintenance facility and security centre, are part of the project.
Truck access was improved by the opening this winter of the Carmen’s Way entrance, which the Federal Bridge Corp. Ltd., says will increase “overall road safety” and keep transport trucks off of small local streets.
