Location: Broadway Bridge lift spans
Schedule: Construction Spring 2022 through Fall 2022
Estimated Cost: $9.3m
Funding Source: County funds for design; anticipated 90% federal and 10% county for construction
The Broadway’s lift span deck is currently made of fiber-reinforced polymer (FRP) structural members. The existing FRP decking on the movable spans is retaining water and the structural beams have begun to fail, resulting in the need for extensive temporary repairs by County maintenance. The deck and supporting beams will be replaced with concrete-filled steel. This is the same type of deck that can currently be seen on the Morrison Bridge.
We will also replace the existing gears, motor brakes, machinery supports and flooring, and the machinery brakes that help control the movable spans. Just like a car, all our movable bridges need brakes to control the speed at which the bridge closes. We will also be upgrading the electrical system to handle the new machinery.
During construction, the streetcar tracks will be removed and put back in place. There will be no change in streetcar operations once the project is complete.
The design phase will begin in Jan 2021 and last about a year. In this phase, we’ll plan how to minimize our impacts on the streetcar and other traffic.
We have applied for federal funding for the construction phase and anticipate notification in Spring 2021.
If the project receives funding, the construction contract will be advertised in late 2021. Construction will be scheduled to begin in Spring 2022 and last through the fall.
The bridge will be closed to all traffic at times during the project. More information will be available after the design phase is complete.
