State Department of Transportation officials say in November they closed the right hand lanes of the Irondequoit Bridge after discovering a problem with steel beams underneath.
Work is expected to start in February to install cover plates underneath the beams.
DOT spokesperson Lori Maher says the Irondequoit Bay Bridge is safe, and they took a couple of months to collect data and come up with a long-term solution.
She says traffic shouldn't be impacted by the work, which will occur underneath the span.
Maher says the Irondequoit Bay Bridge accommodates some 65-thousand cars a day and the DOT will make the necessary investments in the bridge to keep it in a state of good repair so it lasts for several more years.
Repairs are expected to start in February and take six to eight weeks to complete.
Then, Maher says, the bridge will be open to six lanes of traffic.
