The replacement of the Commonwealth Avenue Bridge in Boston could cause 90-minute delays on the Massachusetts Turnpike during Monday morning's commute.

The Massachusetts Department of Transportation will discuss the bridge replacement project and the impact on drivers during a press conference Sunday.

There will be two lanes of travel open on the Mass. Pike in each direction Monday and the MBTA Commuter Rail along with the Amtrak Lake Shore Limited will be open and in service as well.

As construction began over the weekend, officials recommended drivers look for other routes away from the construction work.

The bridge ties Commonwealth Avenue to the Boston University Bridge and it is part of the Green Line B branch tracks. DOT officials plan on finishing the first half of the project by the end of August and the second half in the summer of 2018.

The existing bridge is being demolished as workers replace the bridge deck and the Green Line train deck.

If you're taking Mass. Pike this summer, expect up to 40 min delay

Massachusetts Turnpike drivers heading into and out of Boston this summer will be staring at a traffic nightmare thanks to a complex project that replaces the Commonwealth Avenue Bridge.

Over the weekend there was one lane going eastbound into Boston and two lanes going westbound, out of Boston. The lanes will be expanded to two lanes in both directions on Monday during peak hours.
