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.
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
