Highway 5 Grindstone Creek Utility Relocation

The City has initiated the Municipal Class Environmental Assessment or Class EA process for the relocation of utilities located on the Highway 5 bridge spanning Grindstone Creek and the Canadian Pacific Railway in Waterdown. 

Preferred alternative

To relocate existing utilities to a separate Utility Bridge in advance of the existing bridge rehabilitation, which would allow for an expedited rehabilitation of the existing bridge.

The primary advantages for this alternative include:

  • reduced bridge closure time during rehabilitation thereby minimizing impact to businesses, residents and commuters
  • ease of long term operation and maintenance of utilities as they will be more accessible on a new separate utility bridge
  • the lowest capital cost of the three alternatives that are being considered
  • relatively low construction risks
  • less impact on groundwater
  • no need for property acquisition
  • ease of construction, which satisfies the requirements for the relocation of utilities while balancing the social, environmental and economic considerations
