It's not easy to find construction information on the web -- I think it would be an crazy-convenient thing for PennDOT to provide, but here we are without it.
This isn't much -- http://www.paturnpike.com/news/2009/may/nr050709.htm
Supposedly was to be completed last fall.
Sometime midsummer last year I was riding there, took the hill down to see if I could navigate by foot through the construction -- no -- and climbed back up.
I was just wandering, so I found Abers Creek Rd to cross the turnpike, but if you are trying to connect to Murrysville I don't know.
