SH1 Bombay Interchange Signlisation (PW)

⁠⁠⁠The scope of this project includes the signalisation of the two ramp terminal intersections and the exit from the BP services area. Specifically, this includes the following controls: 

Signalisation of the BP Services Exit

• Signal control of the 2-x eastbound through lanes

• Signal control of the 1 x westbound through lane

• Signal control of the right turn exit from the BP services area

• Stop control of the left turn exit from the BP services area

Signalisation of the Northbound SH1 offramp

• Signal control of the right turn movement

• Stop control of the left turn movement

Signalisation of the Northbound SH1 onramp

• Signal control of the eastbound through lane

• Signal control of the westbound through lane

• Signal control of the right turn to the onramp for traffic from the east

• Give way control of the left turn to the onramp for traffic from the west

Signalisation of the Northbound SH1 offramp

• Signal control of the eastbound through lane

• Signal control of the 2-x westbound through lanes

• Signal control of the right turn from the offramp

• Stop control of the left turn from the offramp

To accommodate the signalisation, the project scope includes the following:

• Demolition of existing raised islands

• Pavement widening and resurfacing

• Stormwater modifications to realign catchpits with modified kerblines

• Construction of new raised islands and kerbs

• Minor service relocations

• Installation of ducting, loops and signal pits

• Line marking
