The two-year long, $27 million Sunny Point project now has Egan Drive on its final route, awaiting only additional striping before the underpass opens.
That may happen late this week, said Soc Kreuzenstein, project manager for the Department of Transportation and Public Facilities.
The new traffic signal on Glacier Highway that leads to the new Egan Drive underpass with the new on and off ramps may be turned on as soon as today, he said.
It will flash "yellow" for several days until motorists on Glacier Highway become used it being there, and then it will begin controlling traffic.
"It will go into flash mode," he said. "That will be a warning to the public that the signal is about to be turned on."
While some of the striping needed for the new ramps has been completed, additional traffic lines need to go down before they can be opened for traffic, Kreuzenstein said.
"We're hoping to get some more paint down soon," he said.
If the weather won't allow painting, reflective tabs can be used as an interim measure. But those won't survive the first snowplowing, he said.
The department's traffic section is likely to soon review the 45 mph speed limit and see when it can be raised, Kreuzenstein said. Though the project is nearly complete for this year, that's not going to happen too soon, he said.
"It's still a construction zone. There's still people moving around," he said.
The project won't be completely finished until work resumes next spring for final landscaping, artwork and other cosmetic parts of the project.
