    Collier Township with the Pennsylvania Department of Transportation (PennDOT) oversight is currently undergoing preliminary engineering efforts for the replacement of the existing bridge superstructure carrying Steen Road over Chartiers Creek in Collier Township, Allegheny County. The proposed superstructure will be simple, composite, steel welded plate girders on unknown reinforced concrete abutments. There will be minor roadway approach work to tie into the new bridge superstructure. The approach roadway will have 11-foot lanes and minimum 2-foot shoulders. The existing bridge width will be maintained. Additional work on this project will include guide rail updates and pavement marking installation.
