Incorporates boardwalks into transportation local aid program and provides for Local Aid Infrastructure Fund grants to boardwalk projects.

S 3456 would incorporate boardwalks into New Jersey's existing transportation local aid program and establish a new Local Aid Infrastructure Fund specifically for boardwalk construction, repair, and maintenance projects. Municipalities with boardwalks - common in coastal communities - would be eligible to apply for state funding through both the amended transportation program and the new grant fund. The bill directly expands eligibility for these structures, which are critical for tourism and public access in beach towns, by adding them to state transportation funding streams. This policy change provides concrete financial support for boardwalk upkeep without altering other transportation funding rules.
