The city is spending more money on the Peace Bridge.
Crews are replacing all the light fixtures as L-E-D lighting will replace the existing fluorescent lights which keep burning out in the winter.
The cost for the work comes in at $700,000, but the city says the new lights are rated to last 15-20 years while the old lights had a 3-5 year life span.
People can still use the bridge as crews will tackle the job on one side of the structure at a time.
The Peace Bridge was built at a cost of more than $24.5 million, and opened 16 months behind schedule in 2012 as bolts had to be re-welded.
