Here are some timeframes from USGS for how long it may take the recent lava flow to solidify, and presumably allow D-9’s to rip and clear accessible roads:
But they do have some good estimates:
• The lava that erupted last year at the average flow thickness of around 33 to 50 feet could take up to 18 months to solidify.
• Lava flows that were 65 to 100 feet thick, however, could take 2 1/2 years to six years to harden.
• And the thickest flows on land of about 180 feet may not fully solidify until 2040.

USGS also has a map of new lava depth in the LERZ, one area along the coast is over 900 feet thick:
