PennDOT officials recently outlined its plans for a dozen construction projects in Blair County this year.

The costliest by far is the $23 million resurfacing, bridge and accessory work on I-99 between the Claysburg-Sproul interchange and the Newry pulloff in Blair, Freedom and Greenfield townships. The project will include seven dual bridge rehabilitations and installation of dynamic message boards. It will extend into mid-2028.

The next costliest project is the $8.4 million pavement restoration and stabilization along 4.6 miles Route 453, Janesville Pike, in Tyrone and Tyrone Township, along with slope stabilization work. The project calls for a 23-mile detour involving Route 865 at Bellwood.
