A Draft Environmental Impact Statement (DEIS) was released for the Intercounty Connector project in December 2004, with a toll feasibility analysis completed afterwards.2 The preferred corridor was the southern alignment.3 A Record of Decision was released by the Federal Highway Administration (FHWA) on May 30, 2006.4
Construction on the ICC began in November 2007 after nearly 50 years of debate on whether to build it.5 The ICC is not planned to be designated as a part of Interstate 370.6 Plans called for the six-lane, $2.4 billion tollway to fully open in 2012. The phases for construction were:7
- Contract A – connect Interstate 370 and MD 97 / Georgia Avenue (7.2 miles, construction from 11/13/07 to Fall 2010; $478.7 million cost)
- Contract B – connect MD 97 / Georgia Avenue with U.S. 29 (7.0 miles, construction from Mid-2008 to Late 2011; up to $460 million cost)
- Contract C – connect U.S. 29 with I-95 (3.7 miles, construction from 1/14/08 to Late 2011, $513.9 million)
- Contract D – construct collector distributor roadway system between ICC and I-95 (three miles at a cost up to $75 million) – construction slated from 2010 to 2011 or 2012
The ICC fully opened between I-370 and I-95 on November 22, 2011. The 1.5 mile extension from I-95 east to U.S. 1 at Laurel opened to traffic on November 10, 2014.
