The bridge is a post-tension box girder structure with the center pier as an arch support straddling the road.

[3] Six cables measuring four inches (102 mm) in diameter run from the arch to the main structure of the bridge at the center.

[2] After more than a decade of studies and designing, construction on the Westside MAX light rail line began in 1993.

[3] The city of Hillsboro required the bridge to be able to cross over the planned widening of the roadway without using a center support column, so as to prevent the kind of accidents that had plagued a previous crossing at the same location,[3][4] a wooden trestle bridge of the Oregon Electric Railway, built in 1917 with a vehicle clearance height of just 10 feet, 6 inches.

[7] The "golden spike" of the Westside light rail line was driven with the final pieces of track of the project installed on this bridge in October 1997.
