Those were among the challenges offi-cials of Bayside, Wisconsin, presented to Bonestroo, Rosene, Anderlik & Associates, a Mequon, Wisconsin-based engineering firm. The project involved an embankment that sup-ports Broadmoor Road and the Union Pacific Railroad where they cross Fish Creek in this upscale suburb north of Milwaukee. Periodic inclinometer readings and cracks in the paved road and curb revealed that the soil behind the rusting sheet pile wall, long con-sidered an eyesore, was moving. The sheet pile, wales, and tie rods had deteriorated to the point where repair was uneconomical.
'The fully exposed metal wall, which was retaining the fill that car-ries the road, was suffering from the effects of years of weathering and nearing the end of its serviceable life,' said lead Project Engineer Mustafa Emir.
The village wanted another way to stabilize the embankment.
