The Idaho Transportation Department is ramping up work on several major construction projects it has under way in Ada County.

Drivers can expect delays at the Gowen Road and Broadway Avenue interchanges and on southbound Eagle Road between Franklin Road and the freeway.

"The upcoming days and weeks will be busy for both workers and drivers. Both construction zones are operating under tight timeframes, heavy traffic conditions and limited space," said ITD Resident Engineer Daris Bruce in a press release.

Here is what you need to know:

• Broadway Avenue I-84 interchange bridge demolition will take place Monday and Tuesday, July 7 and 8. The interchange will be closed 7 p.m. to 5 a.m. each day while crews demolish the old interchange bridge. For the first two to four hours, I-84 traffic will be detoured between the Broadway and Eisenman Road interchanges due to the nearby blasting at Gowen Road interchange. For the rest of the night, only I-84 traffic at the Broadway interchange will be detoured. The area will re-open as soon as the demolition and cleanup are completed; no later than 5 a.m. each morning. Broadway will be reduced to one lane in both directions on both nights.

• Rock blasting near the Gowen I-84 interchange will take place Monday through Thursday, July 6 to 10. I-84 will be closed between the Broadway and Eisenman interchanges from 7 p.m. to 11 p.m. The blasting also will affect traffic on Gowen and southbound Broadway.

• Gowen interchange bridge demolition will take place Friday and Saturday, July 11 and 12. Gowen and the eastbound I-84 on- and off-ramps will be closed overnight each day and traffic detoured from 8 p.m. to 7 a.m.

• A 1.5-mile I-84 stretch west and east of the Gowen interchange is reduced to one lane through October. Eastbound through traffic will cross over to the westbound side, giving crews enough room to rebuild the eastbound bridge at the Gowen interchange. Eastbound motorists intending to exit at the Gowen interchange must move into a dedicated exit lane after the Broadway interchange.

ITD is replacing the Broadway and Gowen interchanges and adding a third lane on I-84 between the interchanges. It is also rebuilding the Meridian Road interchange. Construction will be completed in late 2015.

A summer-long construction project on Eagle Road between Franklin Road and I-84 began Sunday night.

ITD is adding a new southbound lane on Eagle between Franklin and the freeway. The $1 million project also includes adding sidewalk, curb and gutter on the west side of Eagle from Franklin to I-84. New traffic-signal heads and pedestrian-crossing buttons will be installed at the intersections of Franklin, E. St. Luke’s Road and I-84. Construction is expected to be complete by mid-September. The majority of construction will occur overnight, from 10 p.m. to 5 a.m., Sunday through Thursday. At night, lanes will be restricted on southbound Eagle between Franklin and I-84. At least one lane in each direction will remain open during the overnight work. Work that does not interrupt traffic may take place during daylight hours.

In general, access to businesses and residences will remain open throughout construction. Eagle Road will remain open at all times. During construction, residents living near the work zone may expect to hear noise at night from jack hammering, backup alarms, excavation of concrete and other activities.
