Project Description

KDOT is updating the K-18 and I-70 Interchange in Geary County. Several near-fatal crashes have raised concerns about the safety of the current interchange design. Heavy traffic during weekday peak hours and Kansas State University football games further magnifies these safety risks due to congestion. 

KDOT studied several options to improve the intersection from I-70 eastbound to K-18 northbound, and a flyover bridge design has been identified as the preferred option. The flyover bridge will span over the existing bridge across I-70. Additional improvements are planned for the southbound to westbound I-70 onramp. The project will also update the north access point of the interchange and add a two-mile auxiliary lane on I-70 (eastbound only). The existing interchange, including the bridge, will remain open both during and after construction. 

Project Benefits:

• Accommodates future traffic projections
• Reduces congestion
• Accommodates gameday traffic without backing up into the through lanes on I-70
• Accommodates freight
• Has fewer impacts to nearby landowners and does not displace the existing fire station
• Allows drivers to maintain a consistent speed
• Provides improved driving conditions at the K-18/Boller Rd intersection
• Saves the existing bridge, which is in good condition and has significant remaining service life and allows for movement across I-70
• Reduces the amount of lane closure occurrences during construction
