The New Brunswick government hasn't finished negotiations for fixing the two eastbound lanes on the Saint John Harbour Bridge.
The provincial government took over the aging bridge in April in a complex deal with the federal government that saw the tolls taken off the bridge.
The two westbound lanes were refurbished over several months last year, and the eastbound lanes were to be started weeks ago.
The provincial government remains locked in negotiations with the contractor Concreate USL.
The Department of Transportation is saying little about the construction project other than that discussions on the work schedule are underway.
The government official said the situation is "fluid" and would not rule out the possibility the remaining construction would be spread over two years.
Pedestrians, including Jeff Roach, who is an advocate for biking and walking trails in the city, are concerned about losing access to the Harbour Passage walkway, which passes under the bridge.
"I don't know what's happening yet. None of us know what the answers are. And the Department of Transportation has been very silent," Roach said.
Roach said he is also disappointed by the plan for an alternate route to the Harbour Passage walkway during the construction months.
Roach said two traffic lanes should be set aside on Main Street instead of just one as announced by the city earlier this week.
"I would like to see Main Street brought down to four lanes. It just doesn't make sense to me, just observing it and using it, for that road to be six lanes," Roach said.
"I mean we don't even have six lanes on our highway to the suburbs."
The city's proposal to set aside a single lane of Main Street, which is a provincial road, for two-way bicycle traffic awaits approval from the New Brunswick government.
The plan would also see the speed limit on Main Street reduced to 50 km/h.
