The Sir Robert Bond bridge near Grand Falls-Windsor has been patched after photos on social media showed potholes that exposed reinforcement bars on the deck.
The asphalt on the bridge has been patched twice in the past three weeks as wear and tear create cracks in the narrow strip of pavement over the Exploits River.
"This time of the year, every single one of us, we're always frustrated with the potholes," said Transportation and Works Minister Al Hawkins.
"It's been around for years but we've got to find a better way to try to find, I guess, options that will eliminate us having to go back continually."
A new bridge was announced in 2015 and is nearing completion. He said it's expected to be open before the fall.
Hawkins said the bridge will continue to be patched and repaired until the new one is ready for use.
He said the bridge is safe for vehicles to drive across.
"The cold patch we know is really not the best option," he said. "It's really, in a lot of cases, a short term fix."
Hawkins said warmer temperatures will allow better patching techniques like hot asphalt which should last longer between repairs.
