A ride last Sunday took me up to the north side and I returned via Wall, which is closed from Francis to Wellesley and has hardly any traffic from there down to Garland. A zig down the Post hill and a zag west on Montgomery put me on Ash, which is closed from NW Blvd to the bridge. This bridge wouldn't normally be my first choice to cross the river, but traffic was almost zero because nothing's feeding it. Nice way to get through town. John Speare and his buddies hit the bridge a while back right after the approach was paved but before it was open. That must've been a sweet ride.
Over the last couple of years, I've found these types of closures relatively fast and easy to get through and a helluva lot more fun than riding on pavement. There's always a path for the heavy equipment to get through, and it's pretty tightly packed because of their weight. Riding on 28 mm tires also helps . . . these, for me, seem to have the right balance between speed and the ability to handle non-blacktop surfaces.
Of course riding through, while cars are forced to drive around, doesn't feel too bad either.
