Bridge Deck Improvements
The existing deck, built in 1987, had suffered through many northern winters and was starting to show its age. The advanced deterioration of the edge of deck was a safety concern with crumbling concrete and rusting reinforcing steel.The new deck design included a taller, closed parapet to meet current crash testing requirements, improve safety, and keep roadway runoff from corroding the edge of the deck. Additional structural improvements included extending the parapets and the use of asphaltic flumes to prevent erosion around the wing walls.
Staged Construction
Viable detour routes for this portion of STH 64 were over 40 miles long. To reduce impacts to this long truck route, the bridge was redecked in stages. After careful analysis of the geometry of the structure, we were able to maintain a single 13-foot lane on the structure during construction. A single lane of bi-directional traffic was controlled through the work zone by temporary signals. A private entrance was located within the work zone and a temporary signal was phased with the STH 64 signals to provide safe access for the landowner.
Safety Improvements
The new 42-inch closed concrete parapet will provide additional protection for roadway users. An added benefit of the closed parapet is that it will help extend the life of the deck by preventing roadway runoff from deteriorating the edge of the deck. Guard rail for the bridge approaches was also upgraded to provide additional safety for the traveling public.The project was constructed in 2018.Construction Cost: $600,000
