Establishes EDA grant program to support increased business expenses incurred by certain businesses impacted by certain public highway projects; provides 50 percent sales and use tax exemption in impacted municipalities; appropriates $1 million.

This bill establishes a grant program administered by the New Jersey Economic Development Authority (EDA) to reimburse small retail businesses for increased operating costs caused by public highway projects. It specifically targets businesses with 50 or fewer employees located in areas where highway construction blocks traffic or access (called "impacted construction zones"). The grants cover the difference between a business's normal pre-project costs and its actual costs during the project period, based on equivalent business days. Additionally, the bill provides a 50% sales and use tax exemption for businesses in affected municipalities and appropriates $1 million to fund both programs.
