Employees of West Towers work to complete a tower off Oak Ridge Road Friday that will be part of the Mississippi Wireless Integrated Network. A total of 143 towers are being built across the state to improve communication during emergencies. Construction is being funded through $100 million from the Department of Homeland Security. The project is in its second phase, which will place 52 towers in central Mississippi. Phase one saw 44 towers in the southern part of the state, and phase three will see 47 built in the north.
