CEDAR RAPIDS, Iowa (KWWL) -- The City of Cedar Rapids has announced that construction will start on the 16th Avenue SE floodgate. Construction is scheduled to start early to mid-March and the 16th Avenue Bridge will be closed until roughly fall 2020.
During construction, trail traffic will be rerouted to the 12th Avenue Bridge. In addition to the constructing of the gate, the surrounding pavement will be reconstructed to support pedestrian access and trail connections.
The gate will close and lock in place in about 45 minutes protecting the city to the 2008 flood volume. The gate will be about 14 feet high and roughly 67 feet long weighing approximately 61,200 pounds. The project is estimated to cost about $2.4 million.
The 16th Avenue floodgate marks the first Cedar Rapids flood project funded by the U.S. Army Corps of Engineers. A similar gate is planned for the west side of the bridge in 2022.
