In this project, the old pavement was to be removed, a 10-in continuously reinforced concrete pavement constructed, a supplemental drain added, shoulders reconstructed, bridges redecked, the median ground rail replaced by a concrete barrier, acceleration and deceleration lanes lengthened, and signing, lighting and surveillance methods modernized. This article describes how these goals were accomplished while providing a safe environment for drivers and construction workers with a minimum of public inconvenience. Details are given of the traffic control plan, the highway advisory radio (HAR), speed limit, accident experience, and the reconstruction traffic impact. The traffic control plan considered the following factors: motorist and worker safety, Motorist delay in time and money, traffic control costs, extent of work area required for construction, traffic volumes on the main line and ramps, and many other factors. The HAR system was used to encourage motorist consideration of alternative routes or transportation modes by providing advance information concerning closures of travel lanes or interchanges, and information that would afford safer travel. The speed limit was established at 35 mph. Accident experience was monitored. Traffic impacts were monitored continuously by the temporary surveillance instrumentation. Real-time data were used for incident detection and traffic reporting purposes. Counts and congestion records were retained daily for analysis of the traffic pattern changes. The planning and implementation of the overall traffic program on the Eden's Expressway project was considered most effective.
