I-270 and I-95/US 1 corridors north of Washington, D.C. The ICC has six lanes (three in each direction) with variable-width medians and a 60-mile-per-hour design speed. The facility was built to offer 100 percent electronic toll-collection capabilities; tolls are assessed via transponder with no need for vehicles to slow or stop. Allowing traffic to flow between I-95 and I-270 by the end of 2011 was the primary completion target for the ICC project. The project met its goal in November 2011 and stayed under budget. To ensure widespread participation from local contractors, the ICC was divided into four individual contracts, each with separate joint-venture design-build teams. Contract A was a 7.2-mile section that included three major interchanges with 28 bridges, 21,000 linear feet (LF) of noise walls and 530,000 tons of asphalt, bud- The Intercounty Connector (ICC) assesses all tolls electronically via transponder; there is no need for vehicles geted at $478.7 million.
