Signal timing changes underway in Columbia due to I-70 construction delays

On 2026-04-17, Columbia Public Works and MoDOT adjusted traffic signal timing in Columbia, Missouri, to ease congestion caused by ongoing I-70 construction delays and related road closures. Officials said timing changes had been made at East St. Charles Road and Keene Street, with additional changes under evaluation near the Highway 63 Connector. The event reflects a local transport disruption affecting commuter traffic rather than a major system failure.
