James A. Gifford Causeway Update
April 28, 2017
BY TERRY GILLIS
Mr. Peter Neilson from the County of Peterborough was in the Selwyn Council Chambers on Tuesday to give Council and the public an update on the James A. Gifford Causeway repairs.
As a result of the Environmental Assessment (EA) done on the Causeway in 2013 - 2014 the County developed a Pre-loading Contract to begin the process of stabilizing the slope erosion and widening the platform for future lane additions.
The EA determined that the number one priority for the ten year project is to construct a 2m sidewalk and lighting of the Causeway on the north side, create a 3m wide shoulder on the south side and add a 4m extension of rock fill along the south side to surcharge for future 4-laning.
The construction is expected to commence after Thanksgiving weekend and last for approximately two years. The work will reduce traffic to one lane as 185,000 tonnes of rock, 6,000 tonnes of fish habitat spawning enhancement rock, 18 fish habitat stump structures, 16 settlement monitoring stations are constructed and 1,840 metres of steel beam guiderails are replaced with concrete barriers.
The EA identified a number of verified Walleye spawning areas which requires that the work be done during the winter months in order to disrupt the fish population as little as possible. The project is currently awaiting approval from Fisheries and Oceans.
According to Mr. Neilson, this phase of the project (the Pre-loading Contract) is estimated to cost $1 to 2 million.
