The Idaho Transportation Department is working to improve the US-20 Lorenzo Bridge.
ITD has began construction on the US-20 Lorenzo Bridge in Madison County. The bridge rehabilitation construction started in April and is expected to be completed this fall. This rehabilitation will entail re-surfacing of the bridge deck, replacing the guardrail, improving the bridge approaches and finishing with new pavement. This project will greatly improve and extend the lifespan of the bridge. Drivers can expect traffic delays for the duration of the project. Reduced speed limits will be effect and traffic will be shifted over periodically to single lane two way traffic.
