Almost immediately after the parkway was approved by the city, bids were flowing in for new project contracts to construct the new parkways. The Belt system would be constructed via numerous contracts, which involved grading the new parkway, constructing bridges, and paving the new highway. 66 spans of bridges were going to be constructed for the entire system, with the section of the Cross Island Parkway between Fort Totten and the Whitestone Bridge approach being bid on by December 23, 1938. By this point, already seven contracts totaled at over $5 million (1938 USD). S.J. Grover and Sons, a firm based out of Ridgefield, New Jersey got the contract for the section, costing $570,630. Just three days prior, the city got bids for grading the new parkway through the Springfield neighborhood of Queens, crossing between Arthur Street and Brookville Boulevard. This contract also wanted a vehicular bridge constructed over the Cross Island Parkway at Springfield Boulevard and 225th Street. The project went to Petracca and Banco of St. Albans, at a cost of $565,358.35.
