Here's link to a BU Today feature: "BU Bridge Project Nearly Finished - Two new lane configurations being tested"
http://www.bu.edu/today/2012/bu-bridge-project-nearly-finished/
providing diagrams of such configurations. Let's hope that winter weather does not cover the lane markings.
[Note: This was brought to my attention by a notice from the Cottage Farm Neighborhood Association.]
ED: We have done a series on this rearrangement. The most recent, with a summary of prior links may be read at: http://charlesriverwhitegeeseblog.blogspot.com/2012/01/bu-bridge-work-archie-responds-to-globe.html.
