| 609532: CHELSEA- TARGETED SAFETY IMPROVEMENTS AND RELATED WORK ON BROADWAY, FROM WILLIAMS STREET TO CITY HALL AVENUE | Cost Increase | The cost of this project has increased based on the PS&E submission in September 2026. The current project cost reflects the 75% design estimate from January 2026, which did not account for increased landscaping costs, additional signal work to support transit signal priority and bike signals, soil disposal, lighting, and loading zone centers. | HSIP | $12,748,952 | $16,814,797 | $4,065,845 |
| 611974: MEDFORD- INTERSECTION IMPROVEMENTS AT MAIN STREET/SOUTH STREET AND MAIN STREET/MYSTIC VALLEY PARKWAY RAMPS AND MAIN STREET/MYSTIC AVENUE | Remove Project | This project was successfully advertised for construction bids on September 12, 2026. During development of the FFYs 2027–31 TIP, MassDOT had proactively programmed funds in FFY 2027 for this project in the event that readiness risks hindered its advertisement in FFY 2026. Given the project advertised in FFY 2026, this change removes its FFY 2027 funds. | HSIP | $8,295,373 | $0 | -$8,295,373 |
| 616290: ARLINGTON- BELMONT- LEXINGTON- LINCOLN- GUIDE AND TRAFFIC SIGN REPLACEMENT ON A SECTION OF ROUTE 2 | Project Description Update, Cost Decrease | The currently programmed project cost reflects an amount based on Project Review Committee approval in March 2026. The newly proposed cost reflects the final PS&E design estimate submitted in August 2026. The original cost estimate included a substantial contingency based on materials price fluctuations at the time of the preliminary cost estimate calculation. The project was originally planned for delivery in 2030, but was accelerated in development of the 2027–31 TIP due to premature deterioration of the current sign panels. | HSIP | $2,430,960 | $1,659,885 | -$771,075 |
