The minister gave the assurance at a forum of the News Agency of Nigeria (NAN) in Abuja on Sunday, to mark the sixth year anniversary of the present administration.
Records show that construction of the bridge commenced on Sept. 1, 2018 with construction cost put at N336 billion when the contract deal was signed.
The minister, however, made no mention if the construction cost of the facility had changed since the commencement of work.
He said that the project would facilitate influx of investments to the South East when completed.
Fashola said that the construction work had gone beyond the water level, explaining that most bridge works were done under water.
“So, what you see currently is the final work. The sub-structure which entailed building cement structures under water often costs a lot of money.
The bridge is 1.6km long and furnished with other ancillary infrastructure, including a 10.3km highway and an inter-change, expected to be completed next year.
The bridge spans from Asaba in Delta State to Ozubulu, Ogbaru and other communities in Anambra State.
The existing Niger Bridge, linking Onitsha and Asaba was completed in December, 1965.
It was built by the French construction giant, Dumez. (NAN)
