Highway 1 - Cowichan River (Silver) Bridge Painting Project
The southbound silver bridge on Highway 1, over the Cowichan River in Duncan, is having its old paint removed and new silver paint applied.
The side-by-side southbound and northbound bridges recently had seismic upgrades.
Paint on the southbound bridge has deteriorated beyond the means of regular maintenance. Corrosion is beginning to affect the structural steelwork and, over time, may affect its strength. Applying new paint will add many years of useful service to the structure as well as improve the appearance of the bridge.
The project will follow strict environmental guidelines to protect the surrounding area. The bridge will be "shrink wrapped" to contain debris that will be removed daily. The containment system and river environment will be carefully and systematically monitored.
The project will:
- Remove deteriorated paint and corrosion from the bridge to prevent their release into the environment
- Extend the life of the bridge
- Improve aesthetics for users and communities
Painting during the winter season would place a heavy load on the containment system. It is better to do the painting during milder weather.
- Construction will begin in July and is expected to be completed by the end of 2018
- This project follows the seismic retrofit of both bridges
Two lanes will be available along the southbound bridge daily, during higher-traffic periods.
The southbound bridge may be closed from 8 pm to 6 pm when traffic is at its lowest. During this schedule, one southbound lane will be available either on the southbound bridge, or by a detour on the adjacent northbound bridge.
- Southbound bridge vehicle traffic lanes will be open in a narrower configuration to allow room for scaffolding, the containment system, and safe worker access
- There will be a construction speed zone of 30 km/h
- Limited, short-duration traffic lane closures may be implemented and will be scheduled during low traffic volume periods
- Pedestrians may continue to use sidewalk until the first phase of scaffolding installation under the bridge is installed and then the sidewalk will be closed until the work is substantially completed
- The sidewalk and both traffic lanes on the northbound bridge will continue to be available for the duration of project
