Improvements will include: pedestrian buttons for the crosswalks; a dedicated left turn
for the westbound traffic on Rhomberg Avenue to Elm Street; and the reconstruction of
curb ramps to bring the intersection to ADA standards. This newly - rebuilt signal will be

controller equipment, battery backup and mastarms have already been purchased for
the project from other CIPs to eliminate the long lead time in equipment ordering.
