Roads
Rohtak is connected to seven cities by three national highways (NH10, NH71, and NH71A) and two State Highways (SH16 and SH18). National Highway 10 from New Delhi to Rohtak is being upgraded to six lanes with 30 km Rohtak City Bypass, so that the vehicles traveling between New Delhi and Hissar do not have to enter Rohtak city. National Highway 10 from Rohtak to Hissar and several cities of Punjab is being widened to a four-lane highway.
National Highway
Rohtak is well connected to Delhi through NH-10. For better movement of commuters NHAI is widening the highway to six lanes. But the work quality and speed is so poor that the project is being delayed from many years. The construction company is accused many times of using low quality material in construction of roads.
This should be compared with other national highways which were started after this and are operational for full their length.
Rail
Rohtak City is connected to New Delhi, Bahadurgarh Bhiwani, Jind, Gohana, and Panipat by rail. Delhi-Rohtak-Jakhal-Bhatinda railway line is double tracked, the other railway lines are of single track. A new railway line from Rohtak to Rewari via Jhajjar has become operational from January 2013.
The railway from New Delhi to Rohtak has been electrified. EMU service is expected to be operational in June 2012.
Bus
Rohtak is connected to Sirsa, Hisar, Bhiwani, Bahadurgarh, Jind, Gurgaon, New Delhi and other cities by Haryana Roadways and private buses
