CLEVELAND -- First there were security fences popping up all throughout downtown Cleveland.
Now, concrete barriers are being put in place near those steel fences -- some of which have been erected in the middle of E. 9th Street.
The additional security measures were brought in overnight as the Republican National Convention arrives next week.
WKYC has been told the security perimeter should be complete by Saturday evening.
The RNC takes place from July 18-21.
