LAKEWOOD -- Contractor crews widening Interstate 5 and building new overpasses at Thorne Lane and Berkeley Street in Lakewood have a series of overnight lane and ramp closures for the week of May 13.

The work is part of the ongoing I-5 widening project along JBLM.

• From May 13 through May 17, crews will close a single lane of Union Avenue between Thorne Lane and Spruce Street each day from 8 a.m. to 3 p.m. During the work hours, traffic will be controlled by flaggers while crews perform earth work activities associated with the new Thorne Lane overpass.

• From May 13 through May 15, northbound I-5 exit 120 to 41st Division Drive will close from 8:30 p.m. to 4:30 a.m. each following day. Berkeley Street on-ramp to southbound I-5 will close from 9:30 p.m. to 4:30 a.m. each following day.

• May 16, Northbound I-5 exit 120 to 41st Division Drive will close from 9:30 p.m. to 4:30 a.m. May 17. Berkeley Street on-ramp to southbound I-5 will close from 10 p.m. to 4:30 a.m. May 17.

• May 17, Berkeley Street on-ramp to southbound I-5 will close from 10:30 p.m. to 6:30 a.m. May 18.

• May 18, Berkeley Street on-ramp to southbound I-5 will close from 10:30 p.m. to 8:30 a.m. May 19.

Once the new overpass is complete, it will span all lanes of I-5 and the adjacent rail line, elevating traffic over trains.
