Mr Antwi noted that what was left to be done was the concrete work on the second flyover and the completion of the drains and auxiliary roads around the interchange.
The first flyover of the interchange has currently been closed to traffic, but motorists are able to use the lower level.
Currently, work completed is estimated at 80 per cent, as work has begun on the second flyover of the second phase of the project.
The second flyover lies directly on top of the first, linking motorists from the Abossey Okai portion of the Ring Road West to the Awudome portion.
The steel beams meant for the superstructure of the second flyover bridge have been installed.
The construction of the second phase of the interchange started in February 2021.
The first phase, valued at $35 million, was completed in November last year, five months ahead of schedule.
