Introduction
On 22 December 1996 Former Prime Minister H. D. Deve Gowda laid the
foundation stone for the construction of the railway bridge over Ganga at
SonepurThe Digha-Sonpur rail bridge or J.P setu is a bridge across river Ganga,
connecting Digha Ghat in Patna and Pahleja Ghat in Sonpur, Saran district in the
state of Bihar. The rail-cum-road bridge provides easy roadway and railway link
between northern and southern parts of Bihar, it is a steel truss bridge. The bridge
of 4,556 metres (14,948 ft) length is the second longest rail-cum-road bridge in
indai, after Bogibeel Bridge in Assam. This is second railway bridge in Bihar
after Rajendra Setu that connects North Bihar to South Bihar. Indian railways
have constructed two railway stations on either side of the bridge- Patliputra
Junction railway station (PPTA) and Bharpura Pahelja Ghat Junction railway
station (PHLG). Digha-Sonpur Bridge project was executed by Ircon
International and the bridge was completed at Rs 1,570 crore. The electrification
work on the Patna-Sonepur-Hajipur Section was completed by July 2016. The
doubling of railway tracks on the bridge started in May 2018, and is being done
at an estimated cost of Rs 156.09 crore and will be completed by December 2019.
The road bridge was inaugurated on 11 June 2017. Link roads to connect National
Highways on both ends are completed. The total length of construction, including
approaches, is 20km. It is a K-truss bridge. There are two rail tracks and a two-
lane road. Many of long-distance Patna-bound trains going to northeast have
already been shifted to this to this northerly route easing the burden on the heavily
congested Mughalsarai Patna rail line. The buses and commercial vehicles are not
allowed on this bridge yet.
Objectives
To understand the project management of the construction of Digha-
Sonpur Bridge (J P Setu).
To study the road safety measures taken and provide suggestions.
In June 2017, 3M India Ltd. was commissioned by the Bihar Rajya Pul Nirman
Nigam (BRPNNL) and Bihar state Development Corporation Ltd. (BSRDC) to
conduct road safety audits and propose road safety recommendations on
existing and proposed stretches of the project.
Road safety challenges
No Existing traffic safety signboards
Sharp bends which are potential hazards especially in night-time or in fog
No median markings
Objects adjacent to roads, such as tress
Extreme elevated and steep curves
Solutions offered
A road safety audit was conducted
Installation of the following road safety features were recommended:
o Cautionary/Mandatory roads signs to warn of sharpness of road
curves
o 3M flexible Median Markers (FMM) to help with better visibility
in foggy weather and at night
o To implement FMMs for crash barriers on approaching roads
which had more steep and deep curve zones
o Raised pavement markers to clear, definitive outlines of pavement
markings
o Chevron alignment signs to provide additional guidance for traffic,
and to supplement delineators

Results
Accidents and fatalities reduced
Increased visibility of curves and steep ascents and descents during
night-time driving
Drivers can see their travel path from short and long distances
Easy delineation of road; drivers travel well within the road alignment
After successful implementation, BRPNNL started installing 3M FMMs
on new and some older bridges within the state
