The survivor of the crash that killed two others is suing Bettendorf and the designers of the pedestrian path on the I-74 bridge.
Charles Bowen, 22, is accusing the city and WHKS & Co. of negligence by their failure to block vehicles from the entrance of the walkway.
According to the lawsuit filed Monday, the city and the design firm failed to design and include safety systems to warn drivers that vehicles were prohibited from the bike/pedestrian path and failed to design and install barriers to block vehicles.
WHKS is also accused of ignoring guidance from the Iowa Department of Transportation and opened the walkway before it was completed.
