A release on Tuesday night from the Works and Transport Ministry said the temporary closure to traffic is at the 46.48 km mark, north of the Rio Claro roundabout.
Commuters travelling to and from Tabaquite proper to Rio Claro and environs are urged to use alternative routes. They can pass on the Tabaquite Rio Claro Road at the 40.7 km mark onto San Pedro Road and the Naparima Mayaro Road at 34.3 km mark.
The ministry recommends heavy vehicles stick to this route.
