Turkish contractor Yuksel has mobilised more than 4,500 workers for the SR1.9bn ($507m) third and final phase of Riyadh’s bus rapid transit (BRT).

The contract was signed between Yuksel and the client, Arriyadh Development Authority (ADA), in December last year.

The final scope of the third phase of the BRT project includes 22km of road rehabilitation, 17 pair of BRT system stations, 1,353 community bus stops and six pedestrian bridges. It also includes all civil, mechanical and electrical works.

The first phase of the BRT has been completed. Work on the second phase also commenced this year. Local Saudi Constructioneers is implementing the $374m phase two of the project.

Riyadh’s BRT system will complement the $23bn Riyadh Metro, which is expected to be completed in 2019. Both schemes are part of the Riyadh Public Transport Project (RPTP).

In 2014, a joint venture of France’s RATP Dev and local Saudi Public Transport Company (Saptco) won the $1.77bn, 10-year contract to implement, operate and maintain Riyadh’s bus network, which comprises over 100 bus lines and three depots.
