Construction could cause slowdowns along a busy stretch of Interstate 95 this week.

Crews are now working on the interstate between the Beachline and Fiske Boulevard to widen the highway to six lanes.
    
There will be lane closures both north and southbound at night. One runs until 6 a.m. Monday.

There will also be temporary lane closures during the day on State Road 524 under the interstate while crews do work on the highway.
