Reserve lanes |
A modification in design took place right
after at the beginning of the works. Initially, the plans were
for
a 2x2-lane cross-section road with a wide central reserve
for future additional lanes. However, before construction
works began, the client requested that the reserve lanes be
introduced from the start. The result was a 2x3-lane cross
section road.
Service roads |
The project's service roads are two-way
single carriageways. They maintain the circulation of local
traffic and its connectivity with the new dual carriageway
through right-in-right-out junctions, underpasses and
overpasses.
Additional road features
The works also included the following:
·
Retaining walls
·
Barriers and miscellaneous road furniture
·
Signage and road marking
·
Street lighting for the entire road stretch and interchanges
·
Weigh station for trucks
·
Ambulance and police stations
·
Police layby pockets on the road
·
Traffic count stations
Utilities |
Dar made provisions for the relocation or
protection of existing utilities. This was done in full
coordination with the utility owners.
Package 1-B
covers the last 75 km of Section 1. It included one major bypass, one minor bypass and nine interchanges.
Bypasses |
One major and one minor
·
The major bypass avoided the populated urban area of Ibra, with a length of approximately 13 km.
·
The minor bypass is 6 km in length and designed to improve on the alignment.
Interchanges |
Nine interchanges of various types were introduced.
·
They included diamond, dumbbell and trumpet designs.
·
The final interchanges provide for all movements as well as service road connections and access to existing facilities and
structures.
Service road length |
Fifty km-long service roads were used to segregate long-distance traffic from local traffic.
