The restrictions are part of a $63.7 million project covering nearly 17 miles of I-476 between I-76 in West Conshohocken BORO and I-95 in Ridley Township.
The project includes resurfacing travel lanes and shoulders, repairing 49 structures, improving 21 stormwater basins, repairing sound walls and upgrading drainage, pavement markings, signage, guiderail and Intelligent Transportation Systems equipment.
H&K Group Inc., of Skippack, is the general contractor. The project is financed entirely with federal funds.
