The nicer weather is allowing crews to do more road work.
MoDOT is urging drivers to slow down and be aware of those crews making improvements.
April 20-24 is Work Zone Awareness week and MoDOT wants everyone to wear their seat belts and cut of distractions while driving including cell phones.
With the stay at home order in place, officials said there is less road traffic but more people are speeding.
Also, MoDOT has seen an increase in crashes with their TMA trucks (Truck Mounted Attenuator), which act as a barrier between road workers and cars.
"Our employees are taught and do a very good job of always being aware of vehicles, people not paying attention, so those employees are trained to look for that," MoDOT Engineer Brian Untiedt said. "But it's still up to the public and the drivers to watch for our signs and our lights and trucks to do what they need to do when approaching a work zone."
MoDOT said last year there were 39 TMA crashes in Missouri.
So far in 2020, there have been 18.
Drivers are required to slow down or change lanes if possible, when approaching MoDOT vehicles with lights flashing because of the state Slow Down and Move Over law.
Since 2000, 19 MoDOT employees have been killed while working, 13 of them taking place in work zones.
