At TES one of our Certified Traffic Control Technicians will survey your site and then computer generate the traffic control plan.



Used on a two-way/two-lane road where there is one lane on each direction and no median barrier, a flagging operation will keep traffic flowing by  alternating traffic on a single open lane.


This is best when a job requires little to no traffic, like in the case of a mobile crane. A road closure can be placed along with a detour way to keep traffic flowing.


When there is more than one lane, a lane closure can be done by pushing traffic into the remaining open lane(s) creating a safe work environment.


Similar to a flagging operation where there is a single way in each direction but with additional shoulder space, a lane shift can be done to move traffic from both lanes away from the work zone.


There may be jobs where a single spot requires about 15 minutes worth of work before heading to the next one or where a crew will be constantly moving in a slow pace.


TES does events too! From inbound-to-outbound traffic setups around stadiums for games, concerts, and marathons.
