PA: PA 74 Truck Route North of PA 17

PennDOT - District 2 News: PennDOT Designates Truck Restriction on Route 74 in Juniata and Perry Counties 

I need to check how it is signed before putting it in the HB.  It seems to be a northbound only route that just follows PA 17 to US 22/US 322 and then US 22/US 322 west to PA 75.

I will have to fix a sharp angle error since the route goes east to US 22/US 322 WB in Millerstown.

I realize that I forgot the csvs before tonight's update.
