“The Boston Region Metropolitan Planning Organization officially eliminated the Interstate 495/290 reconstruction project from its regional transportation plan Thursday.”
And now it’s dead. For now. They say they;ll try to get it back on the plan next year; I’m sure it’ll get done at some point. Hopefully I won’t have to go through it very often by then.

I drive through this interchange twice a day at least. It sucks (there isn’t a nice way to put it, sorry). From 290, there’s often a backup onto 495 south, which in turn gets backed up because of the proximity of the onramps from 85 & 290, on an uphill grade, followed shortly by the exit to US 20 west.
Northbound on 495 is no better – too many people who decide at the last minute to suddenly cross 2 lanes of traffic to get onto 290, because they didn’t want to wait in the line of slow moving cars on the right.

I-495 first shows as a proposed route from Westboro at MA 9 north to I-95 in Salisbury. By 1961, the section from MA 111 in Boxboro to MA 97 in Haverhill was under construction. The proposal had also extended south to I-95 near Mansfield. By 1966, the highway was built from Rt 9 to MA 110, with sections under construction to the Mass Pike to the south and I-95 to the north. By 1969, the enitre highway from Mansfield to Salisbury was open except for a gap between MA 126 and MA 85 near Milford. This was completed by 1971, and already another proposal was on the maps – an extension southward to the intersection of MA 24 and MA 25 just outside Taunton. Construction began between 1977 and 1979 on this section and was completed by 1986.
In March 2008, a $7.5 million project was approved to add a second lane to each of the ramps to I-90. The work is scheduled to be completed by early December.
