Commuters, this is your final warning: The ride into Boston from the west is about to get rough, as the big construction project to replace the Commonwealth Avenue Bridge returns for its second phase Thursday night.

Here are the highlights:

■  The section of Comm. Ave. over the Massachusetts Turnpike closes to all cars at 7 p.m., as will the intersecting Boston University Bridge.

■  A longer stretch of Comm. Ave., from Kenmore Square to Packard’s Corner, will close to vehicles except for abutters until Aug. 11.

■  Shuttle buses will replace the Green Line along much of this route for the period.

■  Bikers and pedestrians will still be allowed to cross both bridges.

■  The turnpike begins 10 days of lane restrictions along a 1-mile stretch on Friday night at 9 p.m., until Aug. 6.

Stressed already? Check out a full guide to the closures, and some alternative routes for Green Line riders. But, if you can, officials would much prefer you stay clear altogether.

The $110 million project has been in the works for years, and state officials have worked to minimize its effect on commuters by building much of the bridge sections off-site and then installing them during two around-the-clock sprints this summer and last.

The eastbound half of the bridge was replaced over a three-week period in 2017; the westbound side will take just over two weeks this year. Once the structure is replaced, some surface work will continue as long as into next year.
