For the next six months, construction crews will be working to resurface city streets, restore utilities infrastructure and improve transit options for all modes of transportation. The major summer construction projects with traffic impacts are outlined below. All active projects and related traffic impacts are updated weekly on www.boulderconezones.net.

2011 Street Resurfacing Program
The City of Boulder’s annual street resurfacing projects have begun, and are scheduled to continue through the summer and into the fall. About 50 city streets are targeted for chip sealing, resurfacing (overlay) or replacement in 2011 (See all streets planned for resurfacing). In general, these operations will have daytime traffic impacts with intermittent lane/road closures and parking restrictions. Budget and scheduling issues may prevent the city from finishing all of the resurfacing projects currently being considered.

Sidewalk Improvements Program
This project completes repairs to damaged sidewalk and installs or improves pedestrian curb access ramps in a particular neighborhood area each year. This year’s program begins on Tuesday, June 7. Crews will be making improvements to the area bounded by 4th and 9th streets, Alpine and Iris avenues. There will be periodic daytime lane closures associated with this work, as well as short-term impacts to sidewalks and bicycle lanes. This project is expected to be completed by early fall 2011.
Arapahoe Avenue Multimodal Improvements Project
This project will begin in late summer, with traffic impacts expected to last for three months. The purpose of the project is to upgrade Arapahoe Avenue, from Folsom to 30th streets, to include amenities and facilities for all transportation modes. Generally, lane closures will occur during off-peak hours with occasional 24-hour closures as needed. There will also be impacts to sidewalks and transit stops. Detailed weekly traffic impacts will be posted on the Cone Zones website when the work begins.

Broadway (Euclid to 18th) Transportation Improvements Project
Intersection improvements at Broadway and 18th Street (part of the larger improvement project) will begin on Monday, June 6. During construction:
Broadway will be reduced to one lane in each direction, 24 hours a day;
Turn lanes at 18th Street, to and from Broadway, will be closed at times, and detour signage will be in place; and
There will also be occasional closures of the Broadway multi-use path, with bicycle and pedestrian detours in place.
Improvements are expected to take about two months to complete. Work should be done by mid-August, prior to students’ return to campus for move-in week. Construction of the underpass work has been rescheduled to start in late 2011 or early 2012, with the work taking approximately one year to complete.

2011 Sanitary Sewer Rehabilitation Project
This project began in May, and involves the rehabilitation of sanitary sewer lines at various sites throughout the city. In general, motorists can expect intermittent daytime lane closures and parking restrictions where posted. Individual work sites and times will be scheduled on a weekly basis. The project is scheduled for completion by mid-July.

2011 South Boulder Waterline Replacement Project
These projects will begin in mid-June, with traffic impacts expected to last until the end of November. The project involves the replacement of waterlines on:
33rd Street, from Fisher Drive to Walnut Street;
3rd and 4th streets, at Evergreen and Forest avenues;
Chippewa Drive, from Inca Parkway to Mohawk Drive;
Hillsdale Way, from Howard Place to Table Mesa Drive;
Lipan Way, from Inca Parkway to Eutaw Drive; and
Ottawa Place.
Crews will also be installing 1,300 linear feet of new waterlines in Arapahoe Avenue, between 28th and 30th streets. Construction will begin in July and is expected to take approximately a month to complete. The replacement of waterlines will greatly improve the water distribution system and water quality in South Boulder.
