Two streets going one way: As completion of Nampa's new library nears, the city is changing things to make each street bordering the Library Square block a one-way road. To do this, two two-way streets, 11th and 12th avenues, will be converted to one-way between 2nd and 3rd streets, which are already one-way. Eleventh will have three southbound lanes and 12th will have three northbound lanes.
More changes: During the conversion, the city will add parking lanes and sidewalks to both sides of the street. The city is redirecting traffic around Library Square to reduce congestion by increasing the number of lanes traveling both north and south. One-way traffic should improve safety by decreasing the number of potential collision points, according to city officials.
Road construction: Construction will start July 14 and be completed in September. Closures during construction will be limited to one street at a time. During the days, one lane of traffic will be closed; during the night, full street closures will occur from 7 p.m. to 6 a.m. for signal installation and paving.
Business access will be maintained throughout, although some access might be limited during overnight street closures.
Two intersections, at 3rd Street South and 12th Avenue South and at 2nd Street South and 11th Avenue South, will each close for one night during the week of July 14 for intersection improvements. The 3rd Street and 11th Avenue intersection will not be closed, but drivers will see lane closures near that spot.
Library update: Construction should be completed by the end of the year on the $18 million project that includes an $11.6 million, 64,000-square-foot library, a $5.5 million four-level parking garage, and a $1 million public plaza with a water feature.
In April, the Gardner Co., which is developing the Library Square project for the city, announced that it no longer planned its three-story, 30,000-square-foot private office and retail building that would make up a third of the three-part downtown complex. But last month, the company said it was back on board with a scaled-down private office and retail component featuring a one-story, 10,000-square-foot building, including a tower to connect to the parking garage, along with a lobby and restrooms.
The downsized building is expected to be completed by the time the library opens later this year, company and city officials say.
The city is to operate and maintain the library, while the Nampa Development Corp. is to operate the parking garage and plaza. Gardner will own and manage the office and retail space on the block.
