Big Test for Casey Traffic — School’s Back in Session

A new school year starts Tuesday, the first in five decades without a Casey Overpass.

While traffic gridlock has certainly been bad enough this summer, it’s a defensible position to say it could’ve been worse. But with the return of school buses and autumn levels of traffic from motorists, Tuesday could be the beginning of “worse.”

Through June, as drivers were getting used to the new (albeit temporary) traffic patterns, the construction was adding about 10 minutes to afternoon commutes, according to city estimates cited by the Globe.

There are fewer vehicle lanes now than will exist once the bulk of the project is done by Sept. 30, 2016. When the full project is done and all planned lanes operational, state traffic engineers predict it will take cars about 90 seconds longer getting from what is now Shea Circle to Murray Circle, where the Arborway intersects with Centre Street, versus that same trip when the Casey Overpass existed.

Here’s an overview of what the project should look like when it’s done:

    Looked to be smooth sailing from Shea Circle to Murray Circle in both directions for cars at 8:30 this morning (as tweeted).

    I think it’s important to note several other things here:
    when you click through to the Globe’s data charts linked above, you find ONE direction for ONE evening commute experiencing a 10 minute car delay on average through the first five weeks of the overpass being closed. All other masured options were substantially less than that and averages of course include the dramatically adverse conditions during the first week of the closing. Since that time traffic light patterns have been tweaked to improve performance. And even in these charts most trend lines were improving. There may well be better data than this somewhere to support current realities, but the statement that “the traffic gridlock has been bad all summer” doesn’t jive with my experience, and I live a half block away. YMMV, as they say.

    Is Back to School a big test? Sure, and it may get bad this afternoon. But the Casey Arborway certainly aced it this morning.

      Thanks for the detailed report! When I was going through on a bus this morning we got through reasonably well.
