If access to a particular property or properties is controlled by a traffic signal, the Department of Transportation may require that improvements be made to the property within five hundred feet of the department’s right of way which are necessary to improve traffic flow at the intersection controlled by the traffic signal. The required improvements must be limited to lane widening, adding a lane, curb cuts, medians, and similar improvements. Under this section, demolition or alteration of a permanent building on the property must not be required by the department. The property owner is not required to pay for improvements performed by the department.
