Irvine Ranch Water District is converting the northern segment of its Irvine Lake Pipeline to recycled water. During the months of December and January, contractor trucks will be utilizing E. Santiago Canyon Road near Jamboree and the 241 Toll Road to transport dirt and materials. Traffic delays may be possible on Santiago Canyon Road during peak traffic hours.

Red Hill is closed to all traffic over the 405 for repairs to the bridge and surrounding structure. Bikes cannot get through. Current information from the cities say that it will be closed through December 2016 with off-and-on closures into 2017.
Because this is between the 55 freeway and John Wayne Airport there are no good bike-friendly detours nearby. Your best bet is to modify your route to go east of the airport using Irvine Avenue/Campus and Von Karman.
From the Newport Bay Conservancy:
On behalf of the Newport Bay Conservancy, I would like to let you know that Coastal Cleanup Day is Saturday, September 17th, from 9 AM-NOON. Because of this, the path on Back Bay Drive from San Joaquin Hills Road to Eastbluff Drive will be closed during that time.
The County of Orange will be working on the Aliso Creek Trail, repairing and slurry sealing the pavement, from September 2016 through November 2016. The work will take place on weekdays and the trail should be open and available to riders on weekends.

As of August 16, Irvine Blvd. is fully open between Modjeska and Allred, with new pavement, striping and bike lanes (and unfortunately a couple more traffic signals). Enjoy!
There is a detour in effect for the SART about midway between Weir Canyon Road and Gypsum Canyon Road. Riders will need to exit the trail and ride along La Palma in this area. This detour is expected to be in place until December 2017. This sign will be installed by the Army Corps of Engineer’s contractor at entrances to the detour:
The good news is the trail between Lakeview and Tustin is now open, it is no longer necessary to detour on Riverdale.
The San Diego Creek Trail extends from the Upper Newport Bay upstream to the Irvine Meadows Amphitheater. Up stream from going under the 133 Laguna Freeway, the route crosses the creek on a side path of the Spectrum road bridge, then continues along the creek under the 405 Freeway. This bridge has been closed to traffic and cyclist usually crossed in the road, but now is full of parked and moving construction vehicles so share the road. The side path - the wide side walk intended for trail users - has a temporary water pipe right across the path from the fire hydrant. This is a temporary supply but services the water fro the new construction yard at the end of Spectrum road... but may be a trip hazard for a long time. Also there are no painted crosswalks so watch out for traffic now when continuing on the trail across Spectrum, or crossing the road to use the connector to Pacifica.
Irvine Blvd is being widened and curbed between Modjeska and Alton. Traffic is narrowed from 6 lanes to 2. The City of Irvine has done a great job of providing a generous bike lane, as well as slowing traffic speeds through the segments and the pavement is being kept in good shape.
Alton has been narrowed in both directions during construction between to Barranca / Muirlands and Technology. There is a speed reduction, but the bike lane has been narrowed, contained within concrete barriers and the pavement is pretty rough; and as the travel lanes are wearing down, gravel & such is spreading into the bike lanes. Watch for vehicles turning right across your path of travel where the bike lane ends at Muirlands.
South of Modjeska to Allred, one lane in each direction due to construction. There is a reasonable shoulder/bike lane and the speed limit's been reduced, so it is not too bad. Occasionally during the week the bike lane is closed for construction equipment working along the side of the road. There is more road debris than normal due to construction activity.
Road construction has the bridge reduced to one lane in each direction with no shoulder or bike lane.
