Clark County plans to install hundreds of steel posts along the Las Vegas Strip.
Urgency to install the bollards has increased after deadly attacks in which cars has been driven through crowds.
Commission Chairman Steve Sisolak said attacks have made installing the bollards a top priority for the county.
About 700 posts will be added between Spring Mountain Road and Tropicana Avenue.
The bollards will shield areas including the Bellagio fountains, Harrah’s and Paris Las Vegas.
Officials say the posts are strong enough to stop a flatbed truck traveling 55 mph.
The contract with Las Vegas-based Muller Construction is worth nearly $4 million.
Work is expected to begin by early October and will take up to 60 days.
