yesterday traveled in this section and here is the doubling progress
1. mbnr-divitipalli doubling is almost over - hardly it takes 1 month to finish the works
2.divitipalli-jcl -- It may take at least 6 months as highway bridge alignment needs to modified
3....
more... jcl-gollapllalli- works are almost over except near jcl station and removing one manned crossing
So overall, by march we can except entire sc-mbnr as FEDL except jcl-divitipalli
