Glenn Highway’s inbound Muldoon ramp closes for road work
Commuters inbound to Anchorage on the Glenn Highway won’t be able to exit at Muldoon Road this week, due to work being conducted on the new Glenn-Muldoon interchange.
The state Department of Transportation and Public Facilities announced the closure of the ramp from the Glenn to Muldoon on social media. The move is part of work to prepare major Anchorage road projects for the onset of winter.
DOTPF spokeswoman Shannon McCarthy said crews will be installing sensor loops beneath the ramp which detect vehicles and trigger traffic lights at the interchange.
“This last ramp closure southbound off the Glenn started last night; we anticipate it opening Friday morning,” McCarthy said.
Muldoon Road traffic is restricted due to interchange work, but McCarthy said one lane of Muldoon remains open in each direction. Northbound drivers on the Glenn will still be able to exit at Muldoon, but southbound drivers will be diverted to the Boniface Parkway exit.
The $40 million “diverging diamond” project remains on time and on budget, according to McCarthy. Finishing work on the project, set to enter its third and final year in 2018, includes finalizing its landscaping and optimizing pedestrian paths through the interchange.
“I think it was just a really exciting project, in that we were able to keep the old interchange working while we were building new bridges for the diverging diamond,” McCarthy said.
Late-night drivers on the Glenn should expect lane restrictions near the interchange for the next two weeks between 10 p.m. and 5 a.m., as crews demolish Muldoon’s original overpass across the Glenn.
