There are major changes under way along Interstate 30 through Arlington starting this weekend.
Collins Street is undergoing heavy reconstruction at Interstate 30.
Southbound drivers will be detoured at Lamar to the new Center Street bridge.
North-bound traffic along Collins will not be affected.
The detour takes effect today and will last until construction is complete in the winter of 2010.
TXDOT has set up a website with additional information for motorists at www.keep30moving.org
