Commuter alert: South Topeka project begins March 6
TOPEKA, Kan. – A multifaceted project at and around the south Topeka toll plaza at mile marker 177 on Interstate 470 and Kansas Turnpike is set to begin today, March 6, 2017. Construction will include toll plaza improvements, longer acceleration and deceleration lanes coming to and from the interchange, a realigned northbound exit ramp, improved drainage and widening and re-decking the I-470/KTA bridges at mile marker 177.337, which cross over Topeka Boulevard and the BNSF railroad.
In 2017, re-construction of the eastbound I-470/KTA bridge will take place. Beginning in late March, all traffic will use the westbound I-470/KTA bridge where there will be a single, 12-foot lane of traffic in each direction and speed reduced to 65 mph. The toll plaza will remain open during construction with improvements occurring in one to two lanes.
The eastbound bridge, along with the toll plaza and ramp improvements, are expected to be completed in late November, weather permitting. Traffic restrictions will be removed throughout the winter to accommodate snow removal and winter driving conditions. The westbound bridge will be constructed in 2018.
The project contract was awarded to a joint venture between A.M. Cohron & Son, of Atlantic, Iowa, and Hamm, Inc., of Perry, Kan., for $13,998,798.46 in February 2017.
