Boston drivers heading east on the Mass. Pike today are facing a major headache: a fuel spill from a crash has shut down the left lane in the Ted Williams Tunnel. If you’re planning to get across the city, you’ll want to reroute—traffic is crawling and cleanup crews are still on the scene. Message boards are up, but expect delays until things are cleared. It’s a real reminder of how one incident can throw off the whole commute. Anyone else stuck in this mess, or have tips for the best detours? #Transportation #BostonTraffic #TedWilliamsTunnel
