S.R. 101 over U.S. 24

INDOT

Allen County, Indiana

The S.R. 101 over U.S. 24 bridge is part of the interchange at the western end of the U.S. 24 Fort to Port project, Phase 4. LFA prepared construction documents for this 2-span bulb-tee superstructure over the U.S. 24 divided highway. The prestressed concrete bulb-tee beams are 5-ft. - 6-in. tall and span 101-ft. Aesthetic and cost-effective considerations led to the selection of mechanically stabilized earth abutments for this bridge. Integral end bents were constructed for this bridge to eliminate bridge deck joints. The interior support for the bridge is a 5-column frame bent with a crashwall. The substructures for this bridge are supported on 12-in. steel H-piles driven into bedrock. The beams are supported on elastometric bearing pads at the interior support.
