The former site of the speedway is now occupied by the Grounds for Sculpture, a UPS shipping facility, and the housing development known as "Hamilton Lakes".

During his career A. J. Foyt won twelve Indy Car races at Trenton Speedway.

Trenton hosted the NASCAR Grand National and Winston Cup series 8 times: once each May in 1958 and 1959, and once each July from 1967 to 1972, a race known as the Northern 300.

The Northern 300 was placed on NASCAR's 1974 Winston Cup Grand National schedule (Stock Car Racing magazine listed it on the schedule in its early 1974 season issues) but was dropped early in the year and replaced by Pocono Raceway's Purolator 500.

Ray Hendrick from Virginia was the leading winner of these races, driving the Jack Tant-owned number 11.
