Cottonwood Creek Trail Bridge The Cottonwood Creek Trail is the newest addition to Allen's trail network. This $1.2 million trail project was funded with $581,000 in state and county grants and $564,000 from the Allen Community Development Corporation. The Allen Public Art committee also provided $100,000 to enhance the bridge with artwork. The bridge railings feature artwork titled "Current Drift," created by Texas artists Bill FitzGibbons and George Schroeder. Their inspiration for the piece came from a flowing creek through a pastoral setting. The ribbon cutting for this project took place on Feb. 13, 2016.
