Two contractors were hired to assess the structural integrity of the tunnel, and the delay was estimated at two years. The federal government withheld $31 million of funding for the tunnel in July 1985 due to "'wholly inadequate' management of the tunnel's construction". In August 1985, at the instigation of Senator Al D'Amato, the federal government suspended funding on both the 63rd Street and Archer Avenue projects over "concerns with the construction management practices". The two projects had cost nearly $1 billion between them, of which the federal government had provided $530 million for 63rd Street and $295 million for Archer Avenue.
