4th Street from Choctaw Street to Seneca Street

In historic downtown Leavenworth, the City needed to keep a busy 0.25-mile stretch of 4th Street moving while making it safer and more inviting for people on foot. Serving as both US-73 and K-7, the corridor carries steady traffic, including trucks, on four 10-FT travel lanes. Backed by KDOT’s City Connecting Link Program (CCLIP) and a comprehensive traffic study, the City selected a “road diet” that fits downtown. The project shifts the street to three lanes, updates traffic signals, and widens pedestrian space with streetscaping shaped by public input. Strong utility coordination keeps the work on track. BHC reduces risk early by using ground-penetrating radar (GPR) to find unknown utilities, vacuum excavation to daylight infrastructure, dye testing to trace sanitary discharges, and storm sewer camera inspections to guide improvements and support seamless integration with the new streetscape.

This project won the Kansas City Public Improvement Awards from the ACEC of Kansas.
