During the preliminary design phase for this
project, community members voiced several concerns. Their number one concern was
for pedestrian safety. Through a tremendous amount of community involvement and
consideration of their needs and concerns, this project began and ended with
Another concern was that the existing pedestrian
walkway, beneath the Clinton Avenue Bridge, was not compliant with the Americans
with Disabilities Act (ADA). After evaluation of alternatives and various
meetings with the public, which included representatives from the American
Council for the Blind and Regional Center for Independent Living, it was
determined that an elevated walkway would best meet the needs of all
Extensive geometric constraints had to be addressed during
the design of this project and the bridge grade needed to meet ADA requirements.
The clearance required over the various roadways and the limited locations for
bridge substructure elements produced a very complex geometry for the new
bridge. These constraints produced a five-span bridge on a curved alignment. The
bridge has an overall length of 346 feet with spans of 74, 79, 72, 65, and 54
feet. Two radii define the horizontal curvature of the bridge. The first two
spans and a portion of the third span have a radius of 246 feet. The remainder
of the third span and the fourth and fifth spans are on a radius of 98
