Better Roads

The solvency of the Highway Trust Fund is in doubt and MAP-21 will expire on September 30. We can no longer afford to wait. We must act now to ensure our Senators and Representatives know the impact these programs have on their states, districts and the national economy. NSSGA and NAPA are joining forces to guarantee our message is heard loud and clear on Capitol Hill. Don't wait! The time for action is now!
