Doom Race to Oblivion

From publisher blurb: Doom Race to Oblivion takes place on the Lee & Kirby National Bridge. In this Danger Room session, the Team are required to catch and stop the cyborg motorcycle maniac, Speed Metal, from reaching the other side of the bridge. Though they do not know it, Speed Metal has been reactivated by the villain, Dr. Tremendous, and their circuitry implanted with a proximity trigger. Should Speed Metal reach the other side of the bridge, a bomb will be triggered – destroying a large portion of the city.
