Route description

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.

History
Prior to 1971, the portion north of the interchange with the Revere Beach Parkway (current Route 16, previously US Route 1 & MA Route 1A) was originally part of U.S. Route 1. The stretch south of the interchange to the Charlestown Bridge originally had no known route number assigned to it.
When it became designated as Route 99 circa 1971, its southern terminus was on the Charlestown Bridge, but this was moved to its present location following the Big Dig.[citation needed]
The 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]
