If you are traveling from the airport, expect delays.Traveling to Logan Airport and East Boston:Roadways leading to Logan Airport and East Boston are open and available for travel during the Sumner Tunnel/Route 1A South closures. Drivers should follow their normal route:

Logan Airport travel tipsTo reduce traffic congestion during tunnel closures, MassDOT encourages those traveling to or from Logan Airport to leave their cars at home and explore Massport’s list of transportation options to and from Logan, which include: the Blue Line or Silver Line, the Logan Express, the Logan Water Taxi, or the Hingham/Hull Ferry.Vehicles leaving Logan Airport should be aware of ongoing traffic impacts during the Sumner Tunnel closures. Periodically, Massport will close the ramp connecting the airport to the Ted Williams Tunnel and re-direct traffic to minimize the backup on the mainline of I-90. Additionally, vehicles traveling on Route 1A/I-90 westbound towards Ted Williams Tunnel may see one less through lane on I-90 westbound. During some peak traffic periods, one lane is converted to a merge lane to help vehicles leaving Logan Airport to freely join the I-90 mainline. While these changes do not eliminate congestion, they are implemented in an effort to balance traffic volumes during closures of the Sumner Tunnel and provide safer driving conditions inside the Ted Williams Tunnel.Detour optionsIn coordination with local agencies and emergency services, the following detours were determined as the most efficient options to divert traffic away from the Sumner Tunnel while it is closed. When possible, it is highly encouraged to utilize public transit options.Drivers from East Boston seeking to reach the Downtown Boston area will be rerouted to I-90/Ted Williams Tunnel via Bennington Street and onto I-93.https://www.mass.gov/info-details/sumner-tunnel-restoration-project-details-and-closure-schedule

Thanks for your post @ Usa_vxir6w03. The MassDOT have worked with Waze staff for the last 3-4 years on the Sumner closures and they are entered by staff as the closures come due. Just like last summers full time closure, the one’s this summer will be added by staff. Based upon your note, we’ve entered closures, but rest assured, that all Sumner closures are being entered in a timely fashion. There will be, however, times when the crews working will not exactly match the schedule and routing may be affected. However, the times being entered on the closures are those that are published.
