Description
Is there a good reason that at 1485-1491 Massachusetts Ave, Cambridge, MA 02138, the left lane splits into 3 lanes, including 1 that takes the right fork onto Cambridge St, and the right lane only takes 1 lane of the right fork, instead of the right lane taking both lanes off the right fork and the left lane taking both lanes off the left fork?

You may want to resubmit this with a better map location--the map pin is at Alewife Brook Parkway, a couple miles from the location you're discussing!
My guess would be that it's a way of accommodating the traffic running south on Mass Ave that wants to get to Cambridge Street. This makes it a merge and split for those cars, rather than a lane change.

The section of roadway in question is Peabody Street, not Mass Ave. Due to changes to the southern tip of Flagstaff Park and the addition of a bike lane against the right curb of Peabody Street, the cross section was reduced from four lanes to three lanes. In order for a three lane road to split into two two-lane forks, the center lane has to be the decision lane.
Is there a particular complaint you have about the way that this section of road operates? Or were you just curious about why the lanes are configured as they are?

What you are calling the "center" lane is really a left lane from the perspective of someone driving up Mass Ave through Harvard Square. When you are stopped on Mass Ave at Garden Street, I'd rather see the left of the 2 lanes there be required to take the left fork ahead onto Mass Ave, and the right of the 2 lanes be required to take the right fork onto Cambridge Street, like the attached picture shows.
