A summer-long project to add new parkettes, trees, street lights and bicycle parking to College Street between Shaw and Havelock streets begins Monday.
Traffic will be down to one lane in each direction until the project wraps up on October 13, and the 506 streetcar will be replaced by shuttle buses.
In a press release, the city said that a pedestrian walkway will be maintained to allow access to businesses.
It might feel like history repeating itself for the shops and restaurants that line the strip.
A project to replace sidewalks last summer on the same stretch had some business owners complaining that they were being pushed to the brink of closing because customers couldn't access their stores.
The construction was taking so long it was stopped last fall.
The city eventually terminated the agreement with Four Seasons Site Development, the company that was hired to do the work, in October 2016 due to "unsatisfactory performance ... and failure to correct the defaults."
