Summary of the geotechnical and structural problems of the I-495 Bridge
The I-495 Bridge in Wilmington, Delaware experienced geotechnical and structural problems leading to its closure. According to structural engineers, the closure of the bridge was following an external force that caused the four pillars of the bridge to tilt. The 11-mile long bypass through the bridge remains closed for an unknown time. The tilting pillars were because of a shifting force on the earth surface, but the engineers had not yet identified the source. Engineers and workers are using shovels, and high-powered sensors to discover the main cause of the shifts on the ground (Nann, and Jeff 1). After ...
