The new Tay Road Bridge on-ramp will be fully open next month, two months later than planned.
The old approach ramp was demolished in August last year as part of the £1 billion redevelopment of the waterfront.
Construction of the replacement ramps, expected to begin in December 2012, was delayed because of design issues.
The new on-ramp, which links to Dock Street, partially opened last August but was restricted to one lane because of ongoing work.
The approach ramp will fully open next month following a number of changes to the road layout.
Drivers suffered disruption while contractors Sir Robert McAlpine completed the demolition of the old ramp next to Custom House last year.
The council had said they expected construction of the new ramp to be completed by the end of last month after “very wet weather” disrupted the waterproofing.
The work has caused disruption with lengthy queues of traffic on to the bridge at peak hours in recent months.
It was announced earlier this year that major works to resurface and replace expansion joints on the 42-span road bridge planned for next year have been put back by four years.
Work will now take place between 2019 and 2021 after engineers found the 46-year-old asphalt surface, and the expansion joints which are more than 20 years old were in better condition than anticipated.
The full opening of the new on-ramp is the latest step in the regeneration project which has seen the face of the Dundee waterfront change dramatically.
The city’s train station, the old Olympia swimming pool, the former regional council headquarters Tayside House, the Hilton Hotel and the Gala Casino have all been demolished to clear the way for new developments including the £45million V&A museum, a new Sleeperz station hotel and other features.
