All westbound lanes of Interstate 66 will close intermittently between midnight Wednesday, Dec. 17 and 5 a.m. Thursday, Dec. 18, then between midnight Thursday, Dec. 18 and 5 a.m. Friday, Dec. 19 for the installation of gantries between Fairfax County Parkway and Route 28. Each closure will last up to 30 minutes.
Between 11 p.m. and midnight Wednesday and 11 p.m. and midnight Thursday, partial lane and shoulder closures will occur in order to set up the crane.
Message signs will be posted in advance of the work so that motorists can use alternate routes.
The closures are part of the Virginia Department of Transportationâ€™s ongoing effort to install 36 new gantries as part of the I-66 Active Traffic Management System (ATMS). The first gantry went up in mid-November on I-66 East just before Route 28.
The traffic system is scheduled to begin operating between Route 29 in Centreville and the Capital Beltway in early 2015.
