Cedar Falls council approves roundabout, authorizes easements after public safety debate

Cedar Falls’ City Council voted April 7 to approve the Highway 57/Union Road intersection improvement project — a single‑lane roundabout — and to authorize temporary easements needed for construction and to maintain traffic during the work.

The decision followed a public hearing in which neighbors, farmers and emergency‑services advocates raised concerns about access during construction, whether large agricultural equipment could pass the new geometry and how the project would affect emergency response times.

Public works staff described the scope and the easement needs. “The city of Cedar Falls is planning to rebuild the intersection of Highway 57 and Union Road with a single lane roundabout,” Tom, a city staff member, told the council, and he said the design requires temporary easements from about nine properties so traffic can be maintained during construction.

Several speakers asked about how the final roadway would accommodate wide farm equipment. “A lot of the need for temporary easement ... in the northeast corner is to maintain traffic north south in and out of Cedar Falls,” Tom told the meeting. Council members and staff said the finished travel lanes are expected to remain as wide as today and that the roundabout will be designed to allow agricultural machinery to pass. Nick Koppel, district engineer for the Iowa Department of Transportation, said curbing will be sloped for a 45‑mph design and noted that roundabout edges typically do not use the standard vertical curb so larger vehicles have additional room.

Residents pressed whether closing any leg of the intersection for construction would affect ambulance or other emergency traffic. Staff said the planned construction would keep east‑west traffic on Highway 57 open in both directions and maintain north‑side access so ambulances can still enter and leave the city while the south leg of the intersection would be closed for construction. “All access in and out of Cedar Falls would remain,” a staff member said.

Speakers who live near the intersection urged consideration of nearby traffic patterns and enforcement. “If we're going to put this roundabout in, why don’t we put it immediately after that and set it to 35 miles an hour?” said Todd Draper, citing safety and enforcement needs. The council and DOT agreed to monitor operations after construction and to perform a post‑construction speed study; DOT representatives advised letting traffic “shake out” for a period before adjusting limits.

Several speakers also urged the city to consider whether a single‑lane roundabout was sufficient for future traffic growth. Engineers warned that building an oversized (two‑lane) roundabout prematurely can create safety and operational problems; they recommended designing for current traffic with the potential to expand in the future if warranted.

After the public hearing and discussion with DOT staff and the city’s consultants, the council adopted a resolution approving the public‑improvement project and authorizing acquisition of the temporary easements needed to construct the roundabout. Council members voted by roll call; the clerk announced the motion carried.

The design and construction schedule will be carried out jointly with the Iowa DOT, which retains authority over speed limits on Highway 57. City staff said they will return with further details on construction staging, the easement process and post‑construction monitoring.
