According to the supervising bridge engineer, the cracks "did not pose any threat to the integrity of the bridge."[1] During construction of the Southeast Bybee Boulevard MAX Station on the MAX Orange Line, the bridge was widened and elevators and bus pullouts were installed. The station is an island platform located underneath the overpass, with a cupola on the bridge serving as an entrance.[4] Bybee Bridge BioswaleAccording to The Conservation Registry the Bybee Bridge Bioswale, located at the northwest side of the bridge to treat stormwater,[5] was also completed in November 2004.[6] The bioswale contains mostly mowed grass which drains water from the bridge to Crystral Springs. A September 2011 survey of the project showed low invasive species activity but noted the presence of blackberry, morning glory and other weeds. Native plants such as alder, ash, cattail, cottonwood, Douglas-fir, rushes and sedges were also present.[7][8] See also{{Portal|Bridges|Oregon}}
