A major roads improvement project is slated to begin Monday, April 30 in Joshua Tree National Park. Work will include crack sealing, micro-surfacing, chip sealing, pavement repairs as well as new striping and road markings. Construction may occasionally affect parking in campgrounds and turnouts. Minor traffic delays will also be a factor during the months of May and June. Work will take place Monday through Friday (except holidays), between the hours of 6 a.m. and 7 p.m. Traffic delays may be up to 30 minutes in some areas and will also affect shuttle service. Park officials ask visitors to please obey to all signs and notices and be especially cautious around flaggers while traveling through the park. For more information, call Kirk Diamond at 760-367-5680.
