Ernest F. Lyons High Level Design-Build Bridge Replacement

This design-build project consisted of a 4,600lf of span-by-span segmental bridge construction, as well as the construction of two small AASHTO girder bridges to be used for recreational access onto spoil islands.  The high level bridge has a maximum vertical clearance of 65ft and a span length of 152ft.

Top down delivery of precast segments was required to avoid environmental impacts and shallow water barge delivery.
