MARLBOROUGH- HUDSON- RAMP IMPROVEMENTS AND RELATED WORK AT I-495 (SB) TO I-290 (WB)

The proposed improvements include widening the ramp to two lanes and improvements to the ramp alignment. Additional improvements involve minor widening of I-495 to create an exit only lane and a shared through/exit lane as well as widening on I-290 to accommodate the additional ramp lane. The deceleration lane will also be extended primarily through pavement markings. The work will entail resurfacing The I-495 SB and I-290 WB mainline barrels within the project limits to facilitate the changes to the pavement markings. Related work includes associated signage, minor drainage modifications and upgraded guardrail as needed.
