MMM
provided engineering services for approximately 1,500 feet of a two-lane
approach
roadway and a 74 foot-long bridge to span the West Neck Creek.
The bridge, which is on a straight alignment, was designed to
accommodate two 15-foot lanes and a 10-foot bikeway resulting in a total
bridge
width of 44 feet 8 inches. The superstructure consisted
of asphalt pavement supported by 21 inch-deep by 4 foot-wide
precast prestressed concrete slab units spanning approximately
36 feet.
The
substructure
consisted of concrete pile bents and shelf type abutments. The
bridge supports two 4-inch power conduits and three 3-inch diameter
telephone
conduits.
