UPDATE: 5:15 p.m.
The Ministry of Transportation and Infrastructure stresses that the re-opened Highway 3 corridor is only for essential travel and movement of goods.
A brief closure Monday was to conduct a geotechnical assessment after pavement cracking was observed about 10 kilometres east of Manning Park Lodge, damage from the recent storm.
Monitoring is now in place, and motorists should expect sections of single-lane, alternating traffic.
"For drivers who must travel for essential purposes, the ministry urges preparation and patience. Highway corridors between the Lower Mainland and the rest of the province are anticipated to be extremely busy with commercial traffic and at this time of year conditions can change quickly," a ministry statement reads.
Essential purpose checkpoints are in place and those who are deemed non-essential will be turned around.

UPDATE: 4:15 p.m.
Highway 3 has reopened in both directions between Hope and Princeton.
DriveBC made the announcement at 4 p.m.
Traffic has been reduced to single-lane alternating.
Motorists taking the route for essential travel should expect "major" delays.
ORIGINAL: 1:10 p.m.
A new washout has closed Highway 3 between Hope and Princeton.
DriveBC says the critical link is now closed in both directions due to a mudslide seven kilometres east of Manning Park.
Details are limited, but roads contractor Emil Anderson said on social media that crews are responding and traffic is being stopped at both ends.
There is no estimated time of reopening. There is no detour available.
The Hope-Princeton Highway has been the designated route for commercial vehicle traffic between the Lower Mainland and the B.C. Interior since Friday. Usage of the corridor has been limited to essential travel only.
Highway 99, the Duffey Lake Road, remains open and is now the only link between the Lower Mainland and Interior.
