(Springfield, MA) — State transportation officials have unveiled plans for a 260-million-dollar repair of the I-91 viaduct as it moves through Springfield. A crowd gathered Tuesday at the Basketball Hall of Fame to hear about it. Officials say the project could go out to bid in November and take three years to complete. A longer-term study is looking at the possibility of burying the highway or taking it down to grade. The DOT said the current plan for repairs has to move forward now because of safety concerns.
