Weather or construction issues may delay the final paving for this project.What to expect during construction
- Work on your block will not be continuous. Expect crews to finish a portion of work and return at a later date (sometimes months later) to perform a different aspect of work.
- You will have access to your driveway and garage throughout the project, although there may be a slight delay if equipment or steel plates need to be moved to facilitate entry/exit.
- There will be no parking signs placed throughout the project. Please pay attention to the details posted on the signs. Generally, no parking applies during work hours. Some parking may be designated as "staging areas" for storing equipment and materials.
- At the end of each workday, the contractor will place temporary paving or steel plates for public access.
- When a major portion of the project is completed -- or the whole project is done -- the contractor will arrange for "final" paving, followed by striping of lanes and other traffic markings.
