Metro said it will restore several of its bus routes along major roadways in the region at 2 p.m. Thursday after shutting down all service earlier in the day because of the snow and bad road conditions.

The transit agency has about 250 bus routes around the area but had suspended its service because of the snowy weather.

Dan Stessel, a Metro spokesman, said at noon on Thursday that not all of the bus routes would be back in service Thursday. But he expected normal service of all bus routes to be restored by Friday.

In the District, the following bus routes will have some service restored: 32, 36, 52, 54, 70, 90, 92, A6/A8, S2, X2.

In Maryland, the following bus routes will have some service restored: 81, A12, C4, C21, D12, F4, J2, K6, P12, Q1, T18, Y9, Z8.

In Virginia, the following bus routes will have some service restored: 1A, 2A, 3A, 4A, 7A, 9A, 10B, 16A, 22A/25A, 23A, 29N and shuttle service between the Pentagon and Rosslyn stations.

Metro warns riders that even though some service is coming back, it is still possible for there to be delays and detours — depending on the condition of local roads.

The transit agency said it expects to keep running service on these bus routes until 1 a.m. Friday.

Metro’s rail opened on time Thursday at 5 a.m. and did not report any major delays. Weekday ridership on the rail system was down 6 percent compared to the same time last week.

Some bus routes in Montgomery County are also going to be restored later Thursday afternoon. Most of the routes that are re-opening service area hospitals. Buses will run until 10 p.m.

The routes that will operate are Routes 1, 5, 8, 15, 16, 17, 23, 30, 34, 43, 46, 47, 55, 56, 59, 61 and 100. Riders should expect delays with buses running every 30 minutes to 60 minutes, officials said.
