Route descriptionEdit

Route 99 begins where North Washington Street becomes New Rutherford Avenue on the north side of the Charlestown Bridge. This occurs at the intersection with Chelsea Street, situated above the northbound tunnel of U.S. Route 1. Route 99 travels northwestward along New Rutherford Avenue, intersecting with ramps for U.S. Route 1 and passing under the Gilmore Bridge that connects Charlestown to Cambridge. New Rutherford Avenue becomes Rutherford Avenue and the route continues along it, until the route splits off into an underpass below Sullivan Square, where it turns northeastward. The route emerges to join Alford Street and crosses the Alford Street Bridge over the Mystic River. After passing through a small strip of Charlestown on the east banks of the river, the route enters Everett and becomes Broadway.

From Everett, the route crosses through Sweetser Circle (the intersection with Route 16 and Revere Beach Parkway) and continues northeastward into the city of Malden, where it intersects Route 60. The route continues on through a short (0.25 miles (0.40 km)) corner of Melrose before entering Saugus. Once in Saugus the route terminates at ramps leading to U.S. Route 1.

HistoryEdit

The entire route was originally part of U.S. Route 1 before the construction of the Northeast Expressway. When it became designated as Route 99, its southern terminus was on the Charlestown Bridge, but this was moved to its present location following the Big Dig.[citation needed]

Sweetser Circle has been the site of numerous major accidents, including a gas tanker rollover early on December 5, 2007 that resulted in 9,400 U.S. gallons (36 kL) spilling, igniting and destroying 21 vehicles and two large multi-family homes.[2]
