CEDAR RAPIDS — First Avenue will close between Third Street West and First Street East from 8:30 a.m. Monday through the afternoon for installation of a floodgate, part of the city’s $750 million permanent flood control system.
Signed detours will be in place while the street is closed, the city said in a news release.
The closure is needed as a crane places the floodgate on the north side of First Avenue.
The $1 million floodgate is more than 11 feet tall, weighs over 80,000 pounds and requires a 350-ton crane for installation.
When installed, it will be able to roll across First Avenue, lock in place and keep floodwater out of the downtown. A similar gate is planned for the west side of the bridge.
