As one road project ends, another begins in Agoura Hills.

The redesigned $23 million interchange at Kanan Road and Highway 101 is nearly completed, officials say, and the visible construction activity is expected to end by September or October.

September also is when a second project — the widening of Reyes Adobe Road at Highway 101 — is expected to finish its design phase, which means the construction phase will start a few months later, said Assistant City Manager Nathan Hamburger, who is overseeing both road projects.

A contractor for the Reyes Adobe Road construction work will be selected in the fall or early winter of this year, he said.

"Construction is expected to start in the first quarter of 2008," Hamburger said. "Everything is right on time so far."

Construction of the Reyes Adobe Road project is scheduled to be completed around early 2009, he added.

The Kanan-101 interchange broke ground in 2006 after 10 years of planning and preparation. The project is aimed at improving safety through a number of steps, including building loop-type onramps to replace ramps that required drivers to make left turns on Kanan Road.

"The keys to this project are safety and improving traffic," Hamburger said. "Kanan Road now has new loop ramps so that people don't have to turn left across traffic, and it won't cause a backup. Traffic can move in a more efficient manner."

Traffic signals have been relocated, and there is an increase in the number of exit-ramp lanes, he said.

"The average person can see the changes and would think that it's complete," he said. However, there are a few improvements that remain to be done, including landscaping, electrical and signal work. Hamburger said there were no major glitches during the construction process except coordination of the underground utilities, which caused some delays.

Agoura Hills City Councilman Harry Schwarz said he looks forward to the completion.

"Once all the directional signs are in place, it will be a lot better, timely and efficient," Schwarz said.

He said the public will also experience benefits after the Reyes Adobe Road project, which will involve widening the existing bridge from three lanes to six lanes and building bike lanes and sidewalks to increase safety for pedestrians and cyclists.

"This isn't as big of a project as the Kanan Road; it's much simpler, but adding lanes will alleviate traffic for sure," Schwarz said.
