Commuters accustomed to following Hillcrest Avenue to Jackson Street on their way downtown will have to find a new route beginning today.

Jackson Street between Hillcrest and Sunrise will be closed until Sept. 1.

The new closure further complicates travel on Jackson, which already was closed between Sunrise and Berkeley streets while work crews were in the street.

Both closures are part of a project to widen Jackson Street, a main route between homes in the east hills and downtown.
