The Andhra Pradesh Metro Rail Corporation Limited (APMRCL) has issued a Request for Proposal (RFP) to select a consultant for preparing a combined Detailed Project Report (DPR) for a double-decker, four-lane flyover cum metro rail. 

This initiative is part of Phase 1 of the Visakhapatnam and Vijayawada metro rail projects. 

As per APMRCL, the consultant's responsibilities include preparing combined DPRs for the double-decker flyover cum metro rail - spanning 20.16 km (15.1 km + 5.06 km) in Visakhapatnam and 4.7 km in Vijayawada - for submission to the Ministry of Road Transport and Highways (MORTH) and the National Highways Authority of India (NHAI). 

The consultant will also provide assistance to APMRCL and NHAI until the DPR receives approval from MORTH.

It's worth noting that the AP govt previously approved DPRs for Phase 1 construction in three corridors for both Visakhapatnam and Vijayawada metro rail projects, covering 46.23 km and 38.40 km respectively.
