U.S. 69 and 135th Street Interchange

Metcalf Avenue to Antioch Road
and U.S. Northbound 69

Client: City of Overland Park, Kansas

Growth in southern Johnson County in recent years required capacity improvements to 135th Street and modifications to the 135th Street and U.S. 69 interchange to enhance traffic flow. Affinis Corp. was selected to complete the design of the widening of 135th Street to six-lanes and to add an on-ramp from westbound 135th Street to northbound U.S. 69. Our design took into account future plans to expand 135th Street to eight lanes and completely reconstruct the interchange at U.S. 69.

SIGNIFICANT DESIGN ITEMS:

• Eight traffic signals
• Retaining walls
• Reinforced concrete culverts
• Utility coordination
• Public involvement
• Multi-use recreational trail
• ADA ramp design
• Added left-turn lanes
• Street lighting
• Construction traffic control
• Pavement marking and signing
• Fiber optic interconnection
• Dynamic message sign (DMS) installation
• Storm drainage improvements
• New bridge/ bridge widening

COMPLETION DATE: 2005

COST: $9.8 MILLION
