The Big Dig has left a gaping financial hole in the state’s transportation budget that isn’t likely to be filled anytime soon.
A new report is casting doubt on whether there’s a “sinkhole” under the Big Dig after all.
New video released by MassDOT shows the accident that took down ceiling lights inside the Tip O’Neill Tunnel on Wednesday night.
Big Dig officials are digging holes to see how much soil and clay has settled under two of the projects tunnels and to determine whether repairs need to be made.
A drilling operation will measure and test the soil that is settling under the South Station railroad tracks.
Massachusetts transportation officials revealed long-term plans to repair several Big Dig issues on Thursday.
A common ground freezing technique was used when the tunnel was built, but as it has thawed it has created a massive sinkhole.
Two sections of the I-90 connecter tunnel under South Boston are leaking, and at times, there are hundreds of gallons of water rushing in every hour. It’s the biggest leak in the Big Dig.
A day after the void underneath one section of Big Dig tunnel reported, WBZ has now confirmed that there is another leak between two sections of the tunnel under South Boston.
When engineers built the tunnel system, they froze the soil in some places, to keep it from collapsing. Now the soil is thawing, and a space is opening underneath.
