Traffic in Route 30 work zone running smoothly?

I took a drive Wednesday evening to see how traffic is flowing through the work zone on Route 30 in the eastern part of the county. The stimulus project involves repairing and resurfacing the road between the Hallam exit and the Susquehanna River.

Only a section of the westbound side was reduced to a single lane, and it seemed like traffic was moving smoothly. I even saw gaps between the vehicles. We thought that traffic might be backed up even after rush hour. It seems like Route 30 is busy all the time.

So is it always like this? I was out there around 8:30 p.m., and I'm wondering if what I saw is typical.
