Elevated Stretch of National Highway 44

Elevated Stretch of National Highway 44

The National Highway 44 (NH 44) is the longest highway of India, spanning 3,745km from Srinagar to Kanyakumari.

As time moved forward, the cities close to the highway expanded at such a pace that the neighborhoods adjoining the highway mushroomed to very significant numbers.

As a result, the pedestrians and light vehicles along the two sides of the road often affect the flow and speed of long route heavy vehicles. It also poses a big risk for those local lighter vehicles and pedestrians.

To solve this problem, the Highway Authority of India proposed the road widening to be coupled with flyovers over the stretch wherein the highway is running through densely populated towns.

The 34-km long elevated stretch of highway in Nagpur-Hyderabad area is being constructed to improve the road network between Nagpur and the capital city of Hyderabad.

The authorities selected a segmental construction technology for the elevated bridges, and each heavy segment was casted in the quality-controlled environment of precast yards.

Considering the substantial size of these precast segments, it has been necessary to source easy-to-use lifting material, capable of sustaining high loads.

Dextra hot rolled fully threaded bars were the best fit to those requirements.

More than 100 sets of fully threaded (FT) post tensioning bars for lifting and launching of precast segments with launching girder have been supplied for this project, along with accessories such as end nuts and couplers.

Dextra FT Bar systems are frequently used for temporary applications such as heavy lifting and stitching of precast elements and anchoring of steel frame supports.

In the case of permanent applications, the FT Bars can be used for the connection of girders and piers in segmental bridge construction.
