I consider myself pretty lucky to be both living and working in the Dormont-Brookline area—it means I don't spend much time fighting traffic.

But when I worked in Penn Hills, the Liberty Tunnel and all its traffic were just about a daily occurrence for me. If I had a late school board meeting to cover, I could pretty much count on running into a delay because of maintenance work.

PennDOT crews will be doing maintenance work in the northbound Liberty Tunnel tonight, Tuesday, starting at 8 p.m.

Inbound single lane traffic will occur and motorists are advised to use caution, allow extra time and expect changing traffic patterns in the tunnel.

For those of you who work late or make the tunnels part of your daily commute, how will the work affect you?
