who are currently here are presently wrapping up the final document and a report would be tabled to the Minister of Transport and Hydraulics, Mr. Robeson Benn.


A proposed presentation in February of this year during the third Engineering Conference hosted by the Ministry of Public Works held at the International Conference Centre, Liliendaal on the Maintenance and Traffic Management Challenges and discussed the New Demerara Harbour Bridge and its optional locations and cost.


At this conference the proposed new Demerara Harbour Bridge was presented to those present and indicated clearly the options and cost with revenue returns on the project by General Manager of the Demerara Harbour Bridge Corporation, Mr. Rawlston Adams.


Adams’s presentation outlined the structural requirements being reinforced concrete and with a four-lane vehicular path of 20 m wide.
The bridge which would also have a navigation clearance of 100 metres wide with navigational aids, an air draft of 50 metres, adequate marine collision protection at navigating channel and an estimated length of 2,250 metres.
He explained that this structure would see  proposed options in location where two positions are being considered.


Option 1 where the locations proposed are Versailles on the West Bank of Demerara and Houston on the East Bank of Demerara as Option II would see proposed locations at Good Hope on the East Bank of Demerara and Patentia on the West Bank of Demerara.
The access roads would see a cost of US$6.0 M with the bridge structure at a cost of US$225M., and the access road at a total length of 3.0km and a total cost of US$231.0M.
Option I.I will see an overhead ramp which is expected to be at a length of 2.0 km at a cost of US$100.0m totalling the entire option at US$331.0M.


The bridge is estimated to see an annual revenue using existing traffic only at a pessimistic US$ 57.8M which represents 100% of the  Berbice Bridge toll or an optimistic revenue of US$28.9, a representation of 50% of the Berbice Bridge toll or a most likely situation of US$14.45 m a representation of 25% of the Berbice Bridge toll.
Financing is being looked at in two areas as a Public/Private partnership operation similar to the Berbice Bridge construction or the second option in the China EXIM Bank agreement.
