Description

PROBLEM STATEMENT On interstate pavement rehab projects, KYTC often finds it challenging to maintain two lanes of traffic in each direction. The standard practice is to use a full-width shoulder as a thru lane while work is done on adjacent lanes. But difficulties arise when the shoulder is not wide enough to operate as a thru lane — particularly when the required depth for rehabilitation demands more lateral clearance for lanes under construction. Designers can also face maintenance of traffic (MOT) challenges at interchanges due to the widths of mainline bridges, lateral clearances of cross-road structures, and ramp lengths. OBJECTIVES • Review ongoing and completed interstate rehab projects where KYTC found it challenging to maintain desired lane widths during construction. Document negative impacts of MOT on completed facilities. • Develop best practices for MOT to help Project Managers mitigate risks on pavement rehab projects.
