The I-70 Polk-Quincy Viaduct was constructed in the late 1950s. Since then, bridge condition deteriorated, traffic volumes increased, highway design criteria changed and the surrounding area has undergone development. The I-70 Polk-Quincy Project, spanning from MacVicar Avenue to 6th Street, will replace the aging viaduct, ease traffic congestion and improve safety.

Traffic changes will start soon as the Kansas Department of Transportation begins work on the I-70 Polk-Quincy Viaduct, a 2.5-mile reconstruction project extending from approximately MacVicar Avenue to 6th Avenue in Topeka.

 

This construction season will focus on widening I-70 and constructing the new viaduct. Crews are placing temporary traffic control and barrier walls along the 1st Avenue on-ramp to westbound I-70. The ramp will remain open; however, traffic may be stopped briefly at times while equipment is moved. Slow-moving traffic and minor delays are possible.

ROADS AND RAMPS

Access to I-70 on- and off-ramps remains open except for the on-ramp from 3rd Street, which is permanently closed.

BRIDGE REPAIR

Beginning in Spring 2023, KDOT worked to repair existing bridges along I-70 through the area, resulting in adjustments to the lane configurations. 

 

Bridge repair work was completed in Fall 2023. I-70 will remain in its current configuration with one lane eastbound and one lane westbound until the Polk-Quincy Viaduct Replacement Project begins in Spring 2025.
