By State House News Service If President Joe Biden can secure enough congressional support for his $2 trillion infrastructure proposal, Massachusetts officials will need to be ready to take advantage of the funding influx, construction and design industry leaders say. Biden is pushing for a package that would invest hundreds of billions of dollars in the country's roadways, railways, airports and waterways with specific focus on green improvements and environmental justice. He suggested funding the bill, which is under review in Congress, through increased taxes on corporations. The Bay State's ultimate share of the funding could have a "huge impact" on employment and the region's economy, according to Construction Industries of Massachusetts Executive Director John Pourbaix.
