Dubai’s Roads and Transport Authority (RTA) has extended the tender closing date for the second set of two interchanges serving the Dubai Expo site to 28 June.

The new closing date is three weeks later than the previous closing date of 6 June.

The RTA received bids on 18 May for the first set of two interchanges serving the Dubai Expo 2020 site.

The lowest bidder for each interchange as well as the combined price for both contracts is India’s Larsen & Toubro (L&T).

The Expo site, which is opposite Dubai Investments Park on the Jebel Ali to Lehbab Road, will also be served by the Route 2020 metro line.

The RTA signed a AED10.6bn ($2.9bn) contract to design and build the rail link to a consortium of Spain’s Acciona, Turkey’s Gulermak and France’s Alstom in October last year.

For the Expo site itself, Dubai says it will award 47 construction contracts worth AED11bn ($3bn) in 2017. In March the local/UK Al-Futtaim Carillion will be the main contractor for the AED2.2bn ($599m) deal to build the three Theme Districts.
