Construction is ramping up for the summer along the Interstate 35W Corridor Project, and Fort Worth police are warning drivers to obey the 50 mph speed limit through the work zones.
"If you're going too fast you're not going to be able to read the signs of what they're trying to tell you and what the changes are," said Fort Worth Police Officer Tamara Valle.
The project stretches for more than 10 miles, from Interstate 30 south of downtown to North Tarrant Parkway far to the north.
Records obtained by NBC 5 show that, on average, there are more than five accidents each day along the project.
Most of them are minor, but about one each day results in injuries or death.
"Speed is the major factor in that," Valle said. "People need to slow down, remember to slow down."
Fort Worth police see about one fatal accident each week.
"We get accustomed to going one particular way home and to work and when it's changed, you know, we're not paying attention. We're driving a little bit too fast and we end up getting into major accidents," Valle said.
The project won't be finished for another two years, in September 2018.
