The highway is being built at a speed of 100 km per hour.

Raisen | The alignment of the Bhopal-Vidisha National Highway-146 is being improved by eliminating blind turns in the four-lane construction. The old route had curves amidst hills, making it difficult to see oncoming vehicles, increasing the risk of accidents. Now, the hills are being cut down to straighten the road. Along with increasing the width of the road, the four-lane construction will also change its layout. The curves in the hilly areas will be reduced.
