Buses will replace Orange Line service from Oak Grove Station to Sullivan Square Station all weekend, Saturday and Sunday, June 9-10, according to an advisory on the MBTA website.

The buses will make stops at all stations between Oak Grove and Sullivan Square. All shuttle bus stops are accessible for persons with disabilities.

This service change, according to the MBTA, is in place in order for necessary Orange Line track work.

Somerville Patch reported last month that construction on the new Assembly Square Orange Line stop, which has already begun, will lead to periodic bus diversions on the subway line beginning in June and lasting until the station is complete in fall of 2014.
