SOMERVILLE, MA – An arrest has been made in connection with a fatal hit-and-run in Somerville, authorities said Thursday. Edward Clark, 55, of Norwood, was arrested after his truck was found with front-end damage, according to the Middlesex District Attorney's office.

Allison Donovan, 40, a longtime educator, was struck and killed in a crosswalk at the intersection of Powder House Boulevard and Hardan Road Friday night. Police said a pickup truck fled the scene after hitting Donovan and another woman. It was described as a newer model, full-size, black pickup truck, possibly a Ford F-150, with a black cover over the bed and front-end driver's side damage.

The road has been the focus of an ongoing infrastructure improvement project for the past two years, and this spring, sidewalk bump-outs will be installed at North Street to slow traffic approaching from Route 16, and a bike lane will be put in place along the length of Powder House Boulevard.
