Twin Falls, Idaho ( KMVT-TV / KTWT-TV ) Workers for the city of Twin Falls will soon be replacing old water drain culverts that are deteriorating.

The underground channels carry runoff water under sidewalks and alleys into local irrigation canals. Right now there are potentially dozens of culverts that need to be replaced. One of those is on the north side of Addison Avenue between Harrison and Tyler Streets.

Joshua Palmer, Spokesman for the City of Twin Falls, says, "It's going to require a lot of work, because we need to tear up a lot of the sidewalks, part of the alleyways. And replace what is really just old stone and cement with cement block culverts."

Palmer says another culvert at Bracken Street and Filer Avenue also needs to be replaced. He says that process could take up to a month, and he asks drivers and residents to be patient while some alleys and driveways are temporarily closed.
