The 13 km Ghat stretch had been closed for traffic for the last six months for upgradation.
Various organisations had staged a massive protest rally in Sakleshpur yesterday after which NHAI made the announcement that the road would be thrown open to traffic on August 1.
NHAI engineer Raghavan said the work was delayed as it had to be stopped for 20 days in April due to heavy rains. The work was now going on in full swing.
The traffic had been diverted via Charmadi Ghat since the repair works began on the Shiradi stretch, often causing blocks lasting for hours.
The traffic was blocked for around 10 hours on June 14 night in the narrow Charmadi stretch after the tyres of a KSRTC bus got stuck in a drain. Traffic could be resumed only at 9 am yesterday.
