Spur 454 is a long, steep 4-lane concrete boat ramp open year-round at Lake Amistad, featuring a boat dock near the water's edge and amenities including parking and restrooms. The ramp provides access to a 2.

5-mile section of previously submerged Highway 90 that offers opportunities for bank fishing, wildlife observation, and hiking.

Note that boat ramp accessibility depends on lake levels, and all motorized boats require a daily ($4), 3-day ($10), or annual ($40) lake use pass.
