The district is well served by a network of good roads. It has National Highways, State Highways and roads managed by the Zila Parishad. Quite a few roads come under the Hazaribag Mines Board, Forest Department and some small roads are managed by the Damodar Valley Corporation. The Grand Trunk Road (National Highway No.2) covers some important places such as Hazaribag and Barhi. The Barhi-Hazaribag-Ranchi road is a part of N.H. 33 and the Barhi-Rajouli road is a part of N.H. 31.  Even unmettalled graveled roads are open to vehicular traffic throughout the year except on unabridged sections during the rains.Intra state and inter state buses ply regularly on the roads. Thus the district is well connected to other districts of the state as well as to adjoining states of U.P., M.P., West Bengal and Orissa.

The district headquarters at Hazaribag is not directly connected by the rail. The nearest railway station from this town is Hazaribag Road situated at a distance of about 69 Kms. Other important places in district, viz., Patratu and Ramgarh are, however, on the rail head. Ranchi –Koderma railway line is currently under construction.River ways are not common in the district. Most of the rivers are shallow. Generally, they dry in summer though they are in high floods during the monsoon. For these reasons, there is not much of river traffic in the district.There is a fair weather landing air-strip for small planes at Hazaribag, the district headquarters.

For road safety, road signal and road lighting has been and is being installed. Keeping in view the exponential increase in vehicular traffic, widening of roads is envisaged. The total length of pucca road within municipality area is 45 km while that of kutcha road is 168 km. Due to extensive road network within the district and especially the NH 33 which passes through it, the number of accidents has been on an upward swing. The preponderance of heavy vehicular traffic has resulted in an increase in mortality and morbidity associated with motor vehicle accidents.
