Site Photos

Chainage 0.00kmOne arm of the tee-intersection facing New Raipur

Chainage 0.00kmStarting point of the alignment. The road is made of moorum. The initial section is a small village with mud and permanent housing

Chainage 0.100kmThe existing moorum road is wide and has sufficient ROW. On the right hand side is the raised platform for cattle shelter during monsoon

Site PhotosChainage 0.225kmPipe culvert provided along canal forming a cross drainage structure. This is a very temporary measure with no side walls and broken edges

Culvert at chainage 0.750kmC/d structure with head wall but broken canal edge

Chainage 1.000kmCanal on both edges stops. The ROW narrows substantially. The surface condition deteriorates because of paddy field water

Road Design BriefRoad Design BriefSI. Location Issue Design Solutions1 Ch. 0.00km The proposed road is connecting

New Raipur and Aarang the block HQ. The road starts with a Tee intersection. While New Raipur gets developed there will be substantial traffic using this road. Electricity poles are located along the alignment.

The intersection needs to be developed properly for safety. The electricity poles need to relocated.

2 Ch.0.100 to 0.300 km

The section has a pipe laid across the road without any head wall or foundation. This is for the water from the irrigation channels for cross flow. This causes soil erosion in the channel. Because of the pipe the alignment has been adjusted in skew.

^Proper cross drainage structure to be provided. The road has to be realigned.

3 Ch. 0.700 to 0.900 km

Because of the skew in channel alignment the road has been skewed. The channel walls have eroded due to flow of water.

The alignment has to be readjusted. The channel walls need to be protected from erosion.

4 Ch. 0.900 to 1.200 km

Due to agricultural cultivation the road has only the c/w and no shoulders.

Land acquisition/donation will be required to provide for c/w and shoulder. It also needs to be raised to avoid water logging.

Road Design BriefRoad Design Brief5 Ch. 1.200 to

1.300 kmThe foot track is different from the actual vehicle path provided.

Curve needs to be properly designed.

7 Ch. 1.400km The culvert provided skews the alignment.

The culvert has to be redesigned so that proper geometry can be provided to the alignment.
