Background:
The motorway has acted as a barrier within the GAMA road network restricting movement between the North and South sections to three accesses: Ashaiman Underpass, Community 18 Underpass and East Legon Underpass. These have been woefully inadequate resulting in increasing congestion over the years thus increasing travel time drastically.
The Ministry of Roads and Highways in a bid to resolve the challenges commenced with the widening of the East Legon Underpass from a single lane to a dual carriageway. This was completed in August 2018.
The Flowerpot Interchange Project was designed to complement the newly completed underpass and to serve as an alternative for the North South Movement.
The project has been amended severally and now consists of an 802m span flyover which takes off at the Palace Mall and ends on the Boundary Road in East Legon. There will are additional ramps onto the motorway and improvement at the Flowerpot roundabout and its approaches.
Scope of Work:
1. 802m of dual carriageway of the viaduct with asphaltic concreting surfacing.
2. 140m of ramp constructed from Shiashie onto the viaduct towards Airport Hills.
3. 80m of ramp constructed from the viaduct onto the motorway towards Tema.
4. A new road through the old tunnel at East Legon.
5. An additional 200m of road constructed to exit of into Cantonments from the Giffard Road Interchange.
6. Redesign of the Flowerpot roundabout and approaches.
7. Pedestrian walkway on each side of the flyover.
8. Road Furniture (streetlights, road markings and traffic signals.
The works were undertaken by Ms. China Railway No. 5 Engineering Gh Ltd and supervised by Ms. Deoke Consult Ltd.
