from Roy Appleton's DMN blog:

The Bishop Avenue “complete streets” redo will be officially marked at a Nov. 20 ribbon-cutting. Time:10 a.m. Place: Bishop at Colorado Boulevard.
Besides the celebratory words, a time capsule of Oak Cliff memorabilia will be buried nearby. And neighborhood associations, crime watch groups, individuals in City Council District 1 can participate.
“What can your neighborhood contribute?” asks a flier from District 1 Council member Delia Jasso, a project sponsor along with Methodist Dallas Medical Center. “A letter, photograph, a list of current officers, small electronics …GET CREATIVE!!!!”
The capsule will be reopened in 2027, a mere 15 years on. (How will Bishop at Colorado look then?) It measures 12 inches by 12 inches by 16 inches with an opening diameter of 9 inches. So don’t get carried away.
Deliver your items to Jasso’s City Hall office, 1500 Marilla, Room 5FS by 4 p.m. Friday, Nov. 9.
“I’m hoping someone will donate an iPod with music of the time or a flash drive with photographs,” said Gary Sanchez, aide to Jasso.
