Nighttime tests of the Portage Lake Lift Bridge will continue this week as part of ongoing maintenance work.
Motorists should expect delays of 10 to 15 minutes, roughly equivalent to a standard bridge lift for marine traffic.
Test lifts will be limited to taking place between the hours of 7 p.m. and 6 a.m.
Traffic will be allowed to clear and resume normal flow between test lifts.
The project started in mid-December 2014 and was scheduled to be completed by the end of April.
MDOT says recent weather interfered with project completion since dry weather conditions are needed to conduct bridge span balance testing.
The project is now set to be completed by the end of this week.
