COLUMBUS, Ohio -- Fans won't fill the stands, including the new seating area, at Ohio Stadium until the home opener against Virginia Tech on Sept. 6, but this is a busy time at the Buckeyes' football home.

Construction continued Tuesday at Ohio Stadium, with the tunnels from both locker rooms dug up as part of the $13.7 million construction project and 2,600-seat addition to the south stands. The OSU tunnel will be wider than the one in the past with a non-slip surface, so the players can really get going heading onto the field.

Also, crews continue to work on adding permanent lights to the top of Ohio Stadium.

Those lights will come in handy with the Buckeyes hosting three night games for the first time ever in 2014 and more night games certainly ahead in the future. The installation above the east and west walls will "crown" the stadium with high definition sports lighting from MUSCO.

Crews said the installation should continue into next week, with a test of the lights hoped for in the middle of the month.
