The Public Works Department has decided to start tendering process for relaying of over 400 km of road length at the earliest, officials said.
Unhappy over the MCD's poor maintenance of roads, the government had in December last year decided to take over 499 streets with a total length of 863 km from it.
"We will initially spend Rs 350 crore to relay the roads," the officials said.
The civic agency has already handed over 645 km of road to the Delhi government out of the 863 km stretch.
Officials said the most of the roads will be relayed and PWD will look after their maintenance. They said the contractors, after completion of relaying work, will have to carry out their maintenance for a period of five years.
The total length of road network in the city is more than 31,000 km out of which MCD maintains around 27,000 km.
