The Castleton Bridge is located on the longest section of the New York State Thruway that does not have an Interstate Highway designation, between exits 21A (I-87) and B1 (I-90).

It costs at least $1.05 to cross ($1.00 with an E-ZPass discount), by traveling between exits 22 and B1 on the Thruway.

NYSDOT, FHWA and NYSTA have discussed potential strategies to divert peak hour traffic traveling along Interstate 90 between exit 24 and exit B1 to the Castleton Bridge to reduce traffic volumes on the Patroon Island Bridge in Albany.

In 2023, a $47.6 million project was completed on the Castleton Bridge which included the deck replacement of the westbound travel lanes, repairs to the deck on the eastbound travel lanes, replacement of the center median and bridge steel repairs.
