Measure B Group 4 Pavement Rehabilitation

Maggiora & Ghilotti paving work has ground to an extended pause with inclement weather.   Paving should occur through until early 2023. Streets to be paved include most streets south of downtown, in Baltimore Canyon, and South Eliseo Drive. More detailed information is available on the City’s website under ‘fixing our roads. A schedule of planned paving dates for each street is provided; however, please note that the schedule will change weekly as each day that is no suitable for paving will push all paving dates out by a day.
