Beginning July 1, traffic will speed up on some Kansas highways as the speed limit increases to 75 mph.

The new maximum speed limit was passed by the Legislature this year. It allows for the higher speed limit on certain separated, controlled access highways with interchanges.

A committee with the Kansas Department of Transportation selected highways which will receive the higher speed limit.

The highways becoming 75mph are:

• I-70 from the Colorado state line to just west of Topeka in Shawnee County.

• I-135 from a half-mile north of the 85th Street interchange in Harvey County to I-70 near Salina.

• I-35 from U.S. 50 just east of Emporia to a mile east of the Sunflower/Edgerton Interchange in Johnson County.

• U.S. 81 from I-70 near Salina north to K-106.

• U.S. 69 from just six-tenths of a mile north of the north junction of U.S. 54 in Bourbon County to the 199th Street Interchange in Johnson County.

• The Kansas Turnpike from the Oklahoma state line to K-7 in Wyandotte County.

KDOT will put aluminum overlays with the new speed limit over existing 70 mph signs. That will happen on Thursday, June 30th, but officials remind drivers it will not be legal to drive the new speed limit until the law takes effect on July 1st.
