The state Department of Transportation says it's shutting the overpass on the Cambridge side of the BU Bridge on Sunday for some major repairs:
All vehicles will be diverted to the surface roadways and through the BU Bridge/Brookline Street rotary, and back on to Memorial Drive.

There's a traffic circle there. The overpass just lets drivers on Memorial skip the circle. It's going to suck, granted, but it does make sense.

I saw Brookline mentioned and totally misconstrued what traffic was going to do. Just skirting around does make sense, though it'll no doubt cause all sorts of back-ups.

Does this mean they'll finally fix the bulging metal plate on the westbound lane of the overpass? Hit that thing fast enough, I'm sure you can get a little air ...

If you drive 20 going over that bridge then don't complain if you get rear ended.
Hopefully they do fix that jump, I mean bump.

The reduce speed to 20 sign is the direct result of the deterioration of the structure.

The work being done on Western Ave is already creating a huge headache where it intersects with Memorial Drive, and that's scheduled to go on for the next two years. Traffic regularly backs up towards that overpass even during off-peak hours. Fantastic timing!

Considering summer is coming, and the colleges surround there will be closing, and people will be riding bikes or vacationing more, and construction being infinitely easier when its not cold or snowing, it is as perfect as timing for roadwork can get.
Traffic in this area
By Kathode
Sat, 04/06/2013 - 10:22am
Peaks just about now, due to good weather, more tourists and Red Sox games. The BU Bridge rotary is always a gridlock during evening rush hour, especially since the Cambridge to Boston side of the bridge was reduced to one car lane to make room for a bike lane, backing lots of traffic into the rotary. Expect major clusterf*ck. Mass Ave, here I come.

Bike lane didn't reduce the bridge capacity. It is still two lanes at each end and had been functioning with one lane in each direction for several years during reconstruction. The issue with the BU bridge and traffic is the giant clusterfuck of an intersection with Commonwealth Avenue. The signal system there is ancient and the substandard roadway design dates back to the construction of the Mass Pike.

By Kathode

Two lanes to access bridge from either side. Now, there is only one lane to access bridge on either side. More backup ensues including gridlocked rotary on Cambridge side. Not good planning.
You could only get on from one lane at a time
By SwirlyGrrl
Mon, 04/08/2013 - 10:39am
What the bike lane did was remove about 10 or 15 car lengths of sitting in traffic space on the bridge. That's it. Your assumptions of what determines capacity are way off here - you have to look at what is called a RATE LIMITING FACTOR, something all young engineers used to be taught. The rate limiting factor is the STOPLIGHT at the other end, not how many cars can sit motionless on the bridge.
I take it you are not technically employed at MIT?
The inlet was only effectively one lane anyway - even if you could pick which lane you would jam up in - because the input to that two lanes was only one lane.
That area has been a mess since at least the mid-80s - the bike lane didn't change that, other than to make it safe for people to not drive. Blaming an intractable backup on the bike lane is foolish. Traffic happens because there are too many cars for a roadway system - period.
The stop light at the end of
By anon

The stop light at the end of the bridge (assuming a constant car velocity) allows a certain number of cars to pass per unit time per lane. Doubling the number of lanes would therefore double the flux in this simple scenario. To put it another way, while the light is green, cars can go. If there's one lane, you get 1x cars per green light. Two lanes means 2x cars per green light. The true rate limiting factor here is the maximum flux across the bridge when the light is green.
Your point about the inlets to the bridge, however, still stands. As far as I can remember it's always been just a single lane coming out of the rotary and off of Comm Av... though I could be wrong about that. Was it a 2-lane inlet on Comm Av before they built that weird divider thing that blocks off the right turn lane from the traffic going straight westbound?

Consider that gridlock also stalls traffic during rush hour - not just box blocking, but the inability of roadways beyond the green light to take as many vehicles as could theoretically transit the green light.
I suspect there was a second motivation for the bridge itself to be down to one lane - reducing the weight of vehicles on on older structure. (Those lanes were nowhere near wide enough for two buses to pass in tandem anyway).

People who can avoid driving through that area should do so, so those who have to drive for whatever reason can get through the construction easier. Makes sense to me.

Car drivers are not entitled to a fast commute experience just because cars are capable of highway speeds.
If you drive in this area, you get what you get and you either have to find new routes, go multi-modal (combine bike and car or car and transit or bike and transit,etc.), or otherwise adapt when things change (which they really haven't - I used to live in the area years ago and even then it was a mess at any and every time of year). Also, lets see a citation on "more backup since the bike lane" because all that bike lane cost anyone was stuck-in-traffic storage for about 10 cars.
Or, maybe, realize that the root cause of any traffic clusterfuck is too many people who insist on driving their cars into a clusterfuck day in and day out just like you do. No one raindrop thinks it caused the flood, right?

I'll have to take a look before making a judgement, but I'd be very surprised if they did anything sensible with the remaining roadways.
As for the alternate routes:
On Saturday evening, it took about 20 minutes to go the 3 blocks from from Mass Ave/Beacon to Mass Ave/Newbury.
Western Avenue is hosed because of construction.
Last time I checked, the JFK Street bridge was down to 1 lane. (How's it doing these days?)
Land Boulevard is a mess near the Galleria.
Good thing the Longfellow is in such good shape, and can pick up the slack.
