[Pics] Lucknow Metro’s Viaduct – November 1 2015 Update
Just a little more than a year after the bhoomi-pooja for the Lucknow Metro project on September 27 2014, Larsen & Toubro (L&T) – the contractor for the 8.3 km priority stretch of Lucknow’s Metro from Transport Nagar to the Railway Station in Charbagh, has now largely completed the viaduct in the southern section of the line! This includes the portion between Krishna Nagar and Amausi (excluding the station). Only a small section over the Indian Railways’ line is left as you will soon see below.

Wow the finish of the viaduct looks quite good already even without any painting work. Also, I have noticed the viaducts for Lucknow Metro are visibly a lot different (and more aesthetically pleasing) from other metro systems in the country. Is this a matter of just a different design or are they using different technology?
Hi, they’ve used 28m long U-shaped girders to build the viaduct which are precast at a yard. These have a more uniform look than individual segments which are cast together in the same bay, but end up looking quite different than one another.
Similar U-shaped girders can be seen in Delhi (Red line to Ghaziabad, Airport Express line and Violet line to Faridabad) and in Mumbai (Versova-Ghatkopar line).
Hello! Thanks for the prompt and informative reply. Yeah the U-shaped ones really look so much better than the individual segments. And even the pillars in case of U-shaped girders look sleeker as compared to the overall “bulky” look of the individual segments. Wonder why didn’t they decide to use the U-shaped ones for the entire section at Delhi. Do individual segments have any major advantage over the U-shaped ones which made them the preferred choice in the beginning?
I don’t believe there’s any economical advantage, but purely ease/comfort of construction. DMRC woke up to the u-shaped girder only in Phase 2. These require a lot of space for the launching crane to maneuver and place them, so they’ve only been used along the national highways till now (Airport Exp: NH8 ; Violet line to Faridabad: NH2 ; Red line to Ghaziabad: NH24). Interestingly Mumbai Metro used them on one of its busiest east-west suburban roads, but they only carried out launching activity in the night and that too in a much more relaxed completion timeframe.
