With the federal Highway Trust Fund (HTF) unable to support any new highway or transit spending beginning October 1 and warnings from the U.S. Department of Transportation that it will be forced to slow reimbursements to the states starting next month, ARTBA Chief Economist Dr. Alison Premo Black June 6 went to Capitol Hill to brief Senate staff about what it could mean for their states.  She was joined by representatives from the Congressional Budget Office, American Public Transportation Association, and the American Association of State Highway & Transportation Officials.  Dr. Black noted that on average states rely on federal highway funds for 52 percent of all road and bridge capital spending ant that uncertainty surround the trust fund is already adversely impacting the transportation construction marketplace.  She reiterated the need for Congress to take action to provide a long-term solution for the HTF, and to complete timely action on a new highway and transit investment reauthorization bill.
