All lanes reopen in O’Neill Tunnel on 93 north after dump truck overturned, spilled gravel

BOSTON — An overturned dump truck spilled gravel across three lanes of the O’Neill Tunnel on 93 north Monday shortly after 8 a.m., and the traffic impacts have been significant.

Just before 10 a.m. all lanes had reopened in the tunnel.

State Police warned drivers to expect delays and seek alternate routes after the dump truck rolled over on Interstate 93 north, just after exit 23 in the tunnel.

Around 9 a.m., State Police tweeted that the right two lanes of the tunnel had reopened as the dump truck and debris were moved to the left two lanes for cleanup.

Traffic was at a crawl on the northbound side from the tunnel to Quincy. Rerouted traffic was impacting other areas in the city, as Boston Police asked drivers to avoid Atlantic Avenue.
