To reduce on-site construction time to a minimum, a concrete grade-separation structure was designed utilizing precast prestressed components for pier and deck construction. The structure is designed to carry HS20 loading across spans of 103 ft. with a superstructure depth of 3 ft 5 in. On-site construction time was less than three-months.
