Access to Hawthorne Boulevard opens Aug. 7 during Phase IV of the roundabout project at Hawthorne Boulevard and Business Highway 13. Tractor-trailers and semitrailers were detoured and left turns from Hawthorne Boulevard onto southbound Business 13 and left turns from southbound Business 13 onto Hawthorne Boulevard were prohibited during this phase of the project. Construction on the islands east and west of the center circle was completed and the islands to the north and south were still being constructed. Construction of the truck skirt and center circle was underway. The project was estimated to be completed later in August.
