Construction of a Grade Separated Intersection in 56 Days

摘要

The major feature of VDOT's $116M Route 29 Solutions project is upgrading the highly-skewed at-grade intersection at Rio Road. Only 103 days of road closure for cross traffic and no closure of Rte. 29 was allowed for the construction of a bridge and several thousand feet of retaining wall. A structural system that had never before been constructed in Virginia was developed to allow traffic to continue operating throughout construction and delivered in nearly half of the allowable time and well under budget.
