As Mountain Brook is spending time repaving roads and adding more sidewalks, the city is also planning to replace the bridge on Caldwell Mill Road. 

Blair Perry with Gresham, Smith and Partners presented four new bridge options, listed from least to most expensive, to city council members at the council meeting on Aug. 14: a box culvert, a CON/SPAN arch bridge, a flat slab bridge and a precast bridge.

Perry suggested the second option, which is a CON/SPAN arch structure. This design was the second least expensive option and will leave an open bottom for the creek, which requires a lower maintenance than other options. It also comes in pre-cast pieces that can be stacked together and requires little environmental disturbance, creating a faster construction time than other proposed methods, Perry said.

“We think it’s a very aesthetically pleasing structure with the arch in there,” Perry said, agreeing with council president Virginia Smith that they would work to fit the bridge with the city’s current aesthetics. “It’ll look a little like a road just going over top.” 

Perry said they can use a stamping method to create a stone-like architecture to it, and they have planned a walkway for pedestrians. The new bridge will not have any load restrictions, either, which will allow emergency vehicles and additional larger vehicles to safely cross. 

Councilman Phil Black said he was concerned with the amount of drainage the area currently sees, and in response Perry stated they are already looking on how to prevent water from running onto the bridge.

The council approved this bridge selection, and Perry said the plan is to put the project out to bid this fall and follow with construction around the first of the year. Once construction crews have broken ground, it is estimated that the project would be completed in three months.

The next meeting will be on Aug. 28.
