ST. LOUIS - As construction continues on the westbound I-64 double deck structure downtown, engineers have collected information on delays during the past two weeks.
That information can provide drivers the times with the lowest and highest delays through the construction. All information is presuming there are no incidents within the work zone.
Average travel times on westbound I-64 from the MLK split to 21st Street are less than 11 minutes, on average, weekdays before 7 a.m. They climb to about 18 minutes between 7:30 and 8:30 a.m. before dropping to 10 minutes after 8:45 a.m. Traffic is mostly free flowing from 6 to 6:30 a.m. and from about 9 to 10 a.m. each morning, where traveling between the MLK split and 21st Street takes approximately six minutes.
After crews close the second lane on westbound I-64 after 10 a.m., travel times rise to about 10 minutes until 11a.m. From 11 a.m. to 6:30 p.m., travel times range from 17 to 21 minutes. Crashes in the work zone or Cardinal game traffic can significantly increase those delays. After 6:30 p.m., the travel times drop to seven or eight minutes with traffic flowing freely starting at 7 p.m.
"Some of this information is intuitive, but it's important for drivers to know so they can make the best choices to avoid this work, where possible. We still encourage people to shift their working hours, telecommute, use MetroLink or MetroBus services, or use one of the other local bridges into downtown," said Deanna Venker, MoDOT Area Engineer for St. Louis City.
The department continues to work with Illinois DOT to use the overhead message boards on the interstates to warn Illinois drivers of potential delays and to offer alternate routes into St. Louis.
During incidents within the work zone, travel times can range from 25 to 40 minutes.
"We are continuing to monitor the flow of traffic through the work zone and the alternate routes to ensure it flows as smoothly as possible. We are also committed to clearing incidents such as crashes or stalled vehicles within the work zone quickly to help keep traffic moving," said Venker.
