The Menai Suspension Bridge is expected to reopen to some vehicles and pedestrians in the coming days - but only during daytime hours.
The bridge was closed at short notice on Saturday afternoon to all traffic, less than 24 hours after weight restrictions were introduced.
It followed the discovery of bolts on beams underneath the brdige that were in need of replacing.
Heavy traffic was reported around the Menai Bridge and Llanfairpwll areas on Monday morning.
The Welsh Government says talks are ongoing with engineers UK Highways A55 about a partial reopening between 7am and 7pm.
A 3-tonne weight limit would remain in place - effectively banning larger vehicles - with only a single flow of traffic allowed off the island in the morning and onto the island in the afternoon.
Cyclists using the bridge will have to dismount when on the bridge and use the pedestrian footway, while emergency access will be in place for ambulances unable to cross the Britannia Bridge.
The bridge would remain fully closed overnight between 7pm and 7am.
The Welsh Government has apologised to the local community for the inconvenience caused.
A spokesperson added: "Discussions are ongoing with UK Highways A55 DBFO Ltd and North Wales Police and confirmation of timescales and enforcement will be provided as soon as a plan is fully agreed."
"Work is taking place in parallel to undertake the necessary repairs to the bolts. We will continue to provide regular updates when further information is available."
The bridge has remained closed to all vehicles since 2pm on Saturday after police patrols aimed at trying to enforce the 3-tonne limit failed.
Plaid Cymru MP Llinos Medi said: "Following further meetings, I expect more information regarding the partial re-opening of the bridge soon."
Earlier, a trade and customs expert said the temporary closure highighted the "precarious state of the UK's infrastructure".
Josh Fenton from Logistics UK said: "All traffic between Anglesey and the Welsh mainland is now forced onto the Britannia Bridge which will cause inevitable congestion and delays on what is a key trade route between the UK and Ireland."
"There is more than inconvenience at stake: Logistics UK's analysis shows having an HGV stuck in traffic costs the operator £1.29 per minute, and the overall cost of congestion to the UK economy in 2024 was £7.7 billion."
"The situation highlights the importance of building resilience into the UK's supply chain, which is why the government needs to develop a freight and logistics plan to recognise the importance of strategic freight routes, and ensure they are kept open."
