Expansion of prison resumes

Crack in concrete had halted work at construction site

Work has resumed on the 500-bed expansion of the Middlesex House of Correction in Billerica, two weeks after workers discovered a crack in a concrete column that temporarily put the brakes on the $37 million project.

The expansion will add a two-story concrete pod with 256 beds and a single-story dormitory with 240 beds to the 84-year-old facility. State officials say the expansion is temporary and needed to relocate nearly 500 pre-sentence detainees from the overcrowded Middlesex Jail in East Cambridge, while the state seeks to finance and develop a new combined court and jail complex in southern Middlesex County.
