To keep up with the wear and tear, the state Department of Transportation is constantly working on maintenance and improvement projects. The most important of those initiatives are outlined every four years in the Statewide Transportation Improvement Program. The DOT is receiving public comments on the draft version of the latest STIP, to cover the years 2021-2024. The 223 projects listed in the new STIP would cumulatively be funded with approximately $3.9 billion, roughly $3.2 billion in federal money, about $684 million from the state and some $17 million from municipalities. The DOT submits a capital budget request to the state Office of Policy and Management for each two-year cycle, and the General Assembly acts every two years to authorize bonding for DOT’s capital program. The State Bond Commission must also approve DOT requests for funding. Public comment on the STIP will remain open until Oct. 9.
