 Northbound Expressway locked up at a Braintree here. All the way up past Columbia Road. More brake lights. Mass Ave up into the tunnel. Looking at about 43 minutes. Braintree up to Boston. 93 south on to 95 north. Brake lights starting out of Braintree and getting up through that Needham stretch. Got 24, not quite back to 139. 95 a little slow coming up past Neponset Street.
