Lawrence commuters on their way to Topeka or Kansas City may be slowed down by construction that began on Monday.

The Kansas Turnpike Authority announced Friday that it would begin road-improvement projects on the toll road of Interstate 70 between a toll plaza at mile maker 197, near Lecompton, and the Eastern Terminal toll plaza, where the toll road begins at mile marker 217.

Throughout the construction projects, the speed limit in work zones will be reduced to 65 mph, and some lanes and shoulders will be closed. The construction is expected to last until November, subject to weather conditions.

The project includes pavement resurfacing between mile markers 197 and 210, including the Lawrence Service Area at mile marker 209, and lengthening acceleration and deceleration ramps at the Lecompton interchange at mile marker 197 and Tonganoxie/Eudora interchange at mile marker 212.

The project will also include constructing new concrete culverts at mile marker 212 and reinforcing a concrete culvert at mile marker 214.

The first phase of the project began at mile marker 212, according to KTA’s news release.
