Regional road officials rolled out a list of construction projects where commuters will come in contact with cone zones this summer.

Ten local spans of pavement will be scrapped and repaved, and five local roads will be expanded to accommodate better traffic flow — costing more than $34 million.

In Sparks, work will be done at the following locations:

• Greg Street will be paved with durable but expensive concrete pavement from Sparks Boulevard to Vista Boulevard to withstand the burden of heavy truck traffic in and out of the Sparks Industrial Area. Construction on the $5 million project will take place from mid-May to August.

• Rock Boulevard from Victorian Avenue to Oddie Boulevard. RTC will add $2 million in new curbs, gutters and sidewalks from mid-May to August.

• Sparks Boulevard from Prater Way to Baring Boulevard. Northbound lanes will be replaced in this nearly $1.3 million project occurring between late June and August.

• Nichols Boulevard from East McCarran Boulevard to Howard Drive will be reconstructed along with curbs, gutters and sidewalks, and cost $730,000. The start date is uncertain.

Sparks road projects designed to relieve traffic congestion include:

• Pyramid Highway intersection improvements at La Posada and Eagle Canyon drives. This $8.4 million project began last summer and is set to conclude in June.

• North Los Altos Parkway at the intersections of Sparks and Vista boulevards. Construction work started on April 7 at Vista Boulevard to built left-turn lanes on North Los Altos and widen Vista to four lanes about a half-mile north of the intersection. The second part of the project will widen Sparks Boulevard to four lanes of traffic and put up a new traffic signal, concluding in August. There was a temporary intersection and traffic light set up to allow for 24-hour, seven-days-a-week construction work. The $3.6 million project is designed to improve traffic flow.

• Pyramid Highway/North McCarran Boulevard intersection will add a new southbound right-turn lane from Queen Way to McCarran. The project is expected to cost $500,000, and begin and end in September.

Other RTC summer road projects throughout the Truckee Meadows include:

• Kirman Avenue and Sutro Street/Kuenzli Street to Ninth Street

• Mayberry Drive from Fourth Street to the Truckee River, and from Canyon Drive to West McCarran Boulevard

• Mira Loma Drive from East McCarran Boulevard to Rosewood Lakes Golf Course

• Ninth Street from Wells Avenue to Sutro Street

• North Hills Boulevard from Golden Valley Drive to I-80 West

• Wedekind Road from North McCarran Boulevard to Malapi Way

• Virginia Street from Second Street to Meadowood Mall Circle for the public transit system

• Lemmon Drive and U.S. 395 northbound lanes at Memorial Drive

In all road construction areas, commuters need to slow down to ensure the safety of construction workers and themselves, said RTC executive director Gregory Krause.

Beyond summer road construction projects, $4.5 million in road maintenance patching and sealing will be applied to about 150 linear miles of roadways to extend the lives of many cracked and aging roads.

"For every dollar spent on slurry seal, $5 to $6 is saved in pavement reconstruction costs," said RTC engineering director Bob Russell.

This summer, slurry sealing projects will focus in the central Reno and southern Reno regions. Extending a road’s life saves millions of dollars region-wide, RTC officials said.

Another ongoing project is the RTC's coordination with local city governments to retime traffic signals as traffic congestion patterns change.

RTC engineer Jim Poston said regular signal coordination saves commuters money and time.

"We are trying to do traffic signal coordination on major roads every two to three years," Poston said.

He said traffic patterns and congestion change because of new housing, businesses and schools, among other things.

"On average, a driver could save one to two minutes on a 15-minute commute," Poston said. "The retiming of 165 traffic signals has saved hundreds of thousands of vehicle hours, and saved 550,000 gallons of gas on average."

Traffic signals were retimed last year along Pyramid Highway between Interstate 80 and Queen Way.

This year, traffic signals will be retimed along Pyramid from Queen Way to the La Posada intersection, Poston said.
