In the 2005 ACEC Engineering Excellence Awards competition, Urban was presented with an Engineering Excellence Distinguished Award for the Mayor Aitken Bridge project.

Urban replaced the old Mayor Aitken Bridge with a new timber bridge on a new alignment, which vastly improves the substandard roadway geometry of the old bridge in Bridgeton City Park, over Raceway Creek. Timber construction was selected as appropriate for the park-setting. The old bridge remains in place and will be used as a pedestrian crossing. Construction costs were 22 percent less than the estimated cost of $900,000.
