The Bihar urban development and housing department (UDHD) plans to develop a satellite township of Patna on the trans-Ganga side, focusing on Sonepur area in Saran district. Around 500 acres of land near the JP Setu (Digha-Sonpur rail-cum-road bridge) will be utilised. The project aims to alleviate population pressure, traffic congestion, and infrastructure strain on Patna while promoting balanced regional growth. The state is also studying Raghopur diara for inclusion, now connected by road from Patna and soon from Vaishali district. Land survey for the township is expected to start next month. The township will feature world-class amenities: wide roads, green parks, residential zones, commercial hubs, educational institutions, healthcare facilities and sustainable infrastructure. Development will follow the Bihar Urban Planning Scheme Rules-2025, approved by state cabinet. The state plans to build 11 modern satellite and greenfield townships, including Sonpur and Sitapuram near Sitamarhi, alongside extensions near nine divisional headquarters (Chhapra, Gaya, Muzaffarpur and others). Under land pooling schemes, local landowners will potentially receive up to 55% developed land. Two bridges support the plan: the under-construction 6-lane Kacchi Dargah-Bidupur bridge and a four-lane bridge parallel to JP Setu. Patna Marine Drive (Loknayak Ganga Path) will integrate Patna and the new township. The Greater Patna development plan was first proposed by PRDA in 2006, included in the Patna Master Plan 2021, and was later deprioritised in favour of Bihta and Masaurhi development under the Patna Master Plan 2031.

Bihar Urban Infrastructure Development Corporation Ltd (BUIDCO) has proposed a multi-lane road over the Anandpuri drain, from Baba Chowk to Rajapur Pul on Boring Road. The 3.1-km project has two stretches: Baba Chowk to the Atal Path culvert, and near Hanuman Temple on Kasturba Path to the Rajapur Pul drainage pumping station. The proposal was sent to the state urban development and housing department for administrative approval; bidding will begin after approval. Estimated spending is Rs. 1.07 billion, with completion targeted within two years. Work includes cleaning the existing drain, LED street lights, road accessories, street furniture and signage. The drain serves Baba Chowk, Patel Nagar, Atal Path, Patliputra Colony, Pani Tanki, Boring Road, North Sri Krishna Puri, Kasturba Path, Mainpura Digha Diara and Rajapur Pul. A separate 450-metre drain is planned from the environment, forest and climate change office to Nehru Nagar drain.
