After months and months of outbound tunnel closures overnight for renovations, PennDOT has revealed that the inbound tube will get the same treatment.  They're not wasting any time, either.  This round of work starts THIS coming Sunday.

The work will typically require a full inbound closure overnight until the 6 A.M. hour, although the outbound tunnel project usually was cleared by 5 A.M.  Either way, I don't expect it to cause major problems.

PennDOT-issued release follows:

 
Pittsburgh – PennDOT District 11 announced today that the second phase of work to rehabilitate the Route 3069 (Liberty Tunnel) will begin on Sunday night, Oct. 11. This is the fourth American Recovery and Reinvestment Act (ARRA) project in Allegheny County
 
The $9.8 million project, funded through ARRA, was awarded to the Mosites Construction Company of Pittsburgh, Allegheny County.
 
Phase 2 includes structural concrete repairs in the northbound (inbound) tunnel and ventilation shaft improvements and updating/repair of electrical systems in both tunnels. Other minor improvements will also occur.
 
To allow the necessary work to occur, the inbound Liberty Tunnel will be closed from between the Liberty Bridge and Route 51, Sunday through Thursday from 10 p.m. to 6 a.m. through late August 2010. Outbound traffic will not be affected at this time. Signs will be posted to guide motorists.
