Chicago Skyway Bridge

F.H. Paschen Construction was awarded a contract to replace deteriorated bridge piers supporting the Chicago Skyway Bridge at 95th Street. Temporary bridge supports were designed and constructed to maintain the bridge deck in its position while existing piers were removed and new piers constructed in their place. Traffic volumes and vehicular loading imposed upon the temporary pier supports was a concern. HBE was contracted to perform continuous monitoring of the bridge deck to assure there was no settlement or lateral movement during the critical period between pier demolition and replacement. Because of the traffic volume on the Chicago Skyway it was decided to close I-90 for 15 minutes around 3 a.m. once a week to allow our survey crews to perform monitoring operations. Since monitoring was to be performed in total darkness to strict tolerances conventional survey equipment could not be used. To meet this challenge HBE had prism targets attached to the bridge deck at various locations and survey crews used laser instrumentation to measure any bridge deck movements. The bridge piers were successfully replaced. The bridge is now undergoing major bridge deck improvements.
