LITTLE ROCK, Ark. — Lately, there's been construction everywhere you turn.

Arkansas currently has projects under construction all over the state.

In the Little Rock area, you may have noticed all this work being done along 630.

It’s a continuation of the Big Rock interchange project and it’s raised a lot of questions from Little Rock residents.

Carlie wrote into 11 Listens, asking why the state department of transportation is building new lanes on 630 when I-30 between I-40 and 530 are unbearably rough.

We took Carlie’s question to Danny Straessle, the spokesperson for AR DOT.

“Based on the data out there, how old is the pavement, how many cars are there, what’s the accident rate... all types of formulas; that’s how it’s decided where the money gets spent,” said Straessle.

Straessle said a lot of thought goes into what projects are completed and how they are funded.

Right now, crews are expanding I-630 to four lanes in each direction between the Big Rock interchange and University.

We learned the work is being funded by the half-cent sales tax voters approved back in November of 2012. That created a 1.8 billion dollar construction program.

“We could go out and tear up a two-lane highway that carries 25 vehicles a day, rebuild it… but for only 25 vehicles a day, is it worth spending 24-40 million dollars to do just that?”

Money’s tight, so the commission has to make data-driven decisions based on things like:

  • Traffic flow
  • Accident volume
  • Density of traffic

“These are some critical decisions that we have to make when we decide where a lot of that money gets spent. It’s not political… it’s data-driven,” Straessle said.
