Installing three sided arch

SR 26 over Longcliff Creek is Precast Forum's thrid Indiana DOT project.  Even with the tight constraints within the powerlines, all 19 truck loads were installed in one day.  The crossing was a 20' span x 11' rise three sided arch with precast headwalls and wingwalls.  The wingwalls and headwalls were designed for guardrail attachment.

This INDOT structure consisted of 130 linear feet of 42' Span x 11' Rise Precast Three Sided Arch Bridge Units.  This project, SR 44 over Gibson's Ditch,  used a pedestal wall foundation to achieve the required waterway area and also to bury the foundation below scour depth.  It included precast headwalls and precast wingwalls.

This INDOT stream crossing on SR 25 required a 45 degree skew with limited right-of-way.  With the use of skewed end units and sloped headwalls, Precast Forum was able to create a layout that would fit within these constraints.  The crossing consisted of 85 linear feet of 24' Span x 9' Rise Three Sided Arch Bridge Units
