Lee County Electric Cooperative (LCEC) contractor MasTec crews began the second phase of its island infrastructure upgrade this week along Tarpon Bay Road. Crews completed phase one on Sanibel Captiva Road last week. The second phase work will continue through Nov. 21 at which time it will be suspended for peak season on the islands. Work will resume after Easter 2014. Poles are being replaced with concrete posts along with any aging power lines.
