Heavy commercial vehicles could be compelled to use the planned Nairobi–Mombasa Expressway, where motorists will have to pay tolls to use the road.

This is meant to ease congestion on the existing highway, address safety issues that the road has faced over the years, and reduce wear and tear.

Construction of the Sh352 billion 440-kilometre dual carriage road, which has been branded Usahihi Expressway, is expected to begin by the end of this year and take four years to complete.
