A multi-billion road project to Illinois' Interstate 90 in metropolitan Chicago includes rebuilding the commercial truck parking lots with concrete to extend the life of the parking facility. The work is part of the $2.5 billion I-90 Rebuilding and Widening Project between Rockford and Chicago. Removal and full reconstruction of the westbound lanes will allow the tollway to replace old, worn-out pavement with new roadway. The eastbound lanes in this one-mile segment have already been rebuilt.
