This June, we began maintenance on the SW Terwilliger Blvd and SW Bertha Blvd elevated on-ramps to I-5 north. This work improves the weight capacity on the hinges of the ramps, which will maintain long-term safety and use of these heavily traveled on-ramps. Work includes removing and replacing existing bearings with new bearing pads.
Work is temporarily halted and will continue again in 2020.
Why is maintenance needed on these ramps?
Due to the changing nature of vehicle weights, bridge load ratings need to increase to meet current design standards. In addition, the concrete compresses from use over time and needs maintenance. Bearing pads are replaced, and the new pads and hinges are re-encased and inserted closer inside the bridge for increased stability and load capacity.
What are the benefits of the project?
Newly replaced bearings will increase the load capacity of both on-ramps improving our roads and maintain long-term safety by ensuring the on-ramps can continue serving thousands of travelers a day.
