If you work at night, expect a detour tonight in the I-495 / Mass Pike Interchange in Hopkinton and Westborough, which is undergoing a $466 million rebuild. From 11pm tonight through 5am Friday, MassDOT says the 495 southbound exit to I-90 – that’s exit 58 – will be closed. The Detour has you using exit 54A – which is West Main Street in Hopkinton – and then turning around to get onto I-495 going northbound to back to the Mass Pike.
